So why can't it be both? If you are against my product becoming a huge hit after getting off the ground first via kickstarter then moving on to bigger markets with a possible windfall for the creator, and a better product for everyone due to a large IPO, then it sounds more like jealousy than anything else.
People want to feel in close contact with a dev team and part of a special club. If OR had gone on to be a huge company in its own right I don't think that would bother people much, but by getting acquired many of the early backers end up feeling on the outside, the real 'special club' is the one where you need enormous amounts of money to be a member.
Also, while it can be both very often in the real world it becomes one or the other - think of all the not-nice things that corporations o on the basis that their investors' needs come first. You're just going to have a harder time funding stuff if your pitch includes a non-ironic desire to make megabucks because a lot of people will be put off by that.
