But if you implement something in your browser that allows websites to block anything that isn’t an accepted browser (and websites use it because they don’t want their precious data to feed random AIs) you effectively prevent any potential competition from crawling websites to build a search index that might threaten your position.
I’d like to try right a stick for movement and mouse for looking, but with a full controller that doesn’t really work. And so far I haven’t sacrificed a controller to saw off the right side so it can rest on a table with a similar hand position as a mouse.
