To me, telemetry would be like a sofa company wanting to put some cameras in your home to see if you’re using the sofa the way they thought you would. It just feels… off.
“90% of crashes happen right after the player uses a grenade”.
Imo, a simple opt-in crash report gets the job done. Technically it is telemetry, but a crash report is more justified than a “where have you clicked” report.
telemetry data for software from reputable companies does not get sold
There’s just no trust in companies to not sell my data. I cannot trust Microsoft nor Google nor any other company to not sell my data, having seen the shenanigans every single company is willing to pull off to get a cent more a year.
There’s a push towards WebAssembly. Officially it’s not supported yet, but most browsers can handle it. I don’t know how mature the project is though.
But yeah, essentially everything on the web is JS.
