Because it winds people like the OP up. Even if it was a true pain (it is not and likely never will be) then actually I would probably find that kind of fun, and it would still wind people like the OP up.
No online multiplayer? I would actually care more if the devs blocked the option to change the contrast (which my monitor handles anyway).
Free stuff? Sure, more money to waste on other things. Also you don't have to keep it and can redownload it later.
Devs dying? Meh. There always seems to be enough people to make games as a whole broadly profitable. As such there will be investors to do it, and I like enough types of games that I am not going to be overly concerned if the copyright infringement set did manage to take make a niche non viable. Equally there are a lot of games out there now so even if everything stopped being made today, and also all mods stopped being made, and also somehow people forgot how to hack, and also there was no open source/freeware gaming then I would still have enough to play 10 games at once every minute of every day until I die without even scratching the surface. Let alone things I can enjoy continuously -- I listen to music many times over, films I watch again sometimes, TV shows as well, reference books I read over and over and fiction books I can stand to reread from time to time, I am probably at around my 6000th hour of tetris vs mode (I play it when watching films and such) and will occasionally pop in one of the elder scrolls series or something like it to wander around a strange world and killing things/making things.
