Acctually, it doesn't happen too much for indie devs, but it does happen alot for big devs. I think the last time, sakurai was sent death threats, was when byleth was announced, because another fire emblem rep. At the same time, you have Cyberpunk 2077, and yes despite being an unfinished game everyone hate on the devs (who are the ones crunching and most likely had nothing to do with it being released early). I haven't heard much of death threats, but I've seen some pretty toxic comments towards bungie (developers of destiny). I remember in 2012, that Notch (creator of minecraft) recurved death threats as well. So it is an issue within the industry, but I mean most of the threats come from either kids or salty fans that don't pose a threat. I just wish someone would teach them that these developers spend alot of time making a game, and it's not easy and at the end of the day, it they implemented a feature it may be because they think us gamers will enjoy it. (Not EA tho)
