As far as I can tell, they didn't even really make a Discord poll.
The first mention of "spider" (or "IP" or "proxy" or any related words) is from the release announcement of a version which already contains Spider, which got negative reactions: https://i.imgur.com/gLKce8W.png
It's very deceptive wording since "I made an announcement to poll people's reaction" is technically true, but it wasn't a poll or before the changes were made as is implied. Same with "There were very little comments", which leaves out the fact the comments they did get were negative and the low quantity is just from it being a small unknown Discord server.
Or sadly, that commit log standards are nonexistent and don't have to describe the changes and be misleading, it's one of those.
Adding unwitting users' computers to a proxy network by default is so obviously and blatantly unethical, it beggars belief. I'm not angry at the creator, because they seem oblivious. I am, however, extremely saddened and frustrated by their obliviousness. Like in no universe is it ever OK to do this even if nobody responds to your discord poll. It takes a real failure in responsible, ethical upbringing to get here. It takes a lack of consideration and empathy for other people to believe that including this isn't an act of aggression towards everyone who encounters the software.
