it's not that there is not things people could do to ignore the parts of the game that are bad currently and that they're just failing to do so which makes them unnecessarily angry.
it's that for most people, buying odyssey meant an expectation of release level functionality for feet on ground gameplay within the elite dangerous game and the rather conservative expectation that the hallmarks of the game would exist as such into the expansion at the least and ideally improve on them.
what they got was not that. They got a beta that likely wont deliver that release level DLC until the end of the year. Yea, they could do the things less impacted ..but they shouldn't have to avoid the things the odyssey dlc specifically sells... because its actually not done yet. They shouldn't have had to wait for months while it got even as functional as it currently is. And the people who chose not to shouldn't have been negatively impacted the way they were by the release either (as odyssey has introduced regressions in horizons as well as mucked up the bgs cycles and states or changed the behavior in ways that were not warned about - leading to players unsure if things are bugs or working as newly intended).
there's a whole lot to be miffed about, and an actual majority are. Which is an entirely new thing for elite dangerous, as the miffed people used to always be a minority of players. odyssey definitely pushed that scale passed that critical point.
Let's look at it without emotional baggage... It makes great reading but is lacking in substance.
Alpha: Throughout the 6 weeks or so those 'testing' the massively neutered version of EDO were being told that what we had was an old branch of the software and unfinished 'New Planetary Tech' - of which the finished version would be in the release. Performance in alpha was poor and a massive amount of feedback over this was provided to Frontier.
The EDO expansion released (yes, despite the pettiness of this forum, it has been classed as release) with both performance and planetary tech in a worse state than the alpha (obvious as my hardware remains the same in the released version as the alpha - therefore poorer performance is down to the released code, nothing else)
The released expansion is completely unable to run acceptably on the published minimum spec PC - and unlikely to be acceptable on the recommended spec.
(Yes, there were many refunds demanded and the average 'foaming at the mouth' player still continues to behave as if they were mortally harmed by a piece of entertainment software with unexplained issues on release)
Frontier offered no explanation why the released expansion had worse performance than the alpha, nor why the 'final' release of planetary tech displayed effects previously unseen - obvious tiling of assets on some bodies.
Messages were offered us by the CEO - but lacking in content or even a vague explanation why things were so poor.
There followed a few comments designed to placate but did anything but - until the promise was made to 'fix' the problems - although none was offered on planetary tech bar it being suggested that the isse was 'tough'!
The BGS has been 'adjusted' so many times in the past with unexpected results, or at least unpredictable results, that Odyssey may not be entirely to blame, but certainly assisted in the current state as efforts were made to salvage the decimation of Anarchy owned assets apparent immediately following release.
I'm not entirely certain that your claim of "an actual majority" of the players are miffed, from what I've read in the forum there is a very vocal group complaining whose numbers are not particularly large - yes steam has had massively negative reviews - I've even read a few hundred of them - but here, try counting the numbers actively complaining, including yourself, of course - as continual snipes against Frontier are your stock in trade apparently - they are not a majority.
Will Odyssey eventually perform well enough to run on a potato PC and last generation console? Probably, but at a cost to fidelity to make it overall a poor experience I'd be tempted to think.
On an emotional level I admit to hilarity with the behaviour of some people over a piece of entertainment software with serious issues, even purchased at £30 it is less than the cost of a meal for 2 in a mediocre restaraunt ( or 3 in a fast-food joint) and at least, in the fullness of time, should work as intended.
Frontier either had something dramatic go amiss with the 'trunk build' at the 11th hour, or were purposefully misleading players... I'm hoping it was the first.
