That's fine. I just see it as heuristics at different levels. In the wider context, generally, markets work well, so people should be 'allowed' to do all of this. After all, you can choose not to use ETH if you think the foundation sucks. Whether ETH or the foundation sucks is a technical question given your goals, I suppose, rather than a moral one.

In a western legal framework you might argue promissory estoppel if the foundation made certain statements about it, but if you take the libertarian code-is-law stance and you want to be consistent then you probably should have researched exactly what was possible at that level before investing.

So all-in-all, seems fine to me.
