The advertising is quite plain to see. Planets that were used in the video's for Horizons showed variety of colour which is no longer there. They advertised Horizons with the use of colourful planets. Now they are gone - changed to a shade of poop or pink. The advertising did not show this or explain that planets would change in any way in either colour or topography and yet they have.
It is akin to buying a PC advertised with a nvidia 1080 inside but after a few months it suddenly changes to an AMD Fury - Your saying we should now pay for the 1080 despite the product being advertised as including it. No matter how you try to spin this there is no way the community would pay for this.
And once again, just in-case you missed it the first time - Frontier are looking into this so the whole thread is basically arguing a mute point hence I will say no more on the subject except point out you also would like to have stuff for free...
What? So you're saying that all the stuff that appears in the trailers should be available, for free? Just be glad FDev gave a few months of free trial for planetary colours... I'll surely buy a few of those
This isn't a computer dude, it's a dynamic game constantly in development. Of course some things will change from time to time.
As for your last point, I'll just redirect you to an earlier comment of mine in this thread...
It's more like a... Thought experiment.
