The problem is just that a few people didn't know what they bought.
There were some clever folks who asked some questions on the forums when the 2015 LEP was available.
'What if I don't like every expansion?'
'What if they don't release as many expansion as I expect?'
And the answer to that has always been:
'Don't buy it.'
Ah, so we were stupid to pre-pay. Do you think FDev share that view?
I think the plan changed is all, and it has been communicated extremely poorly. And after this long with neither anything to show for it nor any useful information on what's coming (or willingness to provide any) offers of refunds to those no longer happy to wait would be a good way to settle this.
