As an OSS user, and developper, OPT-OUT is a shitty practice. It should be opt-in to users who face crashes issues if they want to share that data (they care enough to provide their info to the dev to fix it). I know this makes users sound entitled, but otherwise the “opt-out” permission will be exploited by someone which will make users even more paranoid about OSS apps.
The landscape is changing so fast thanks to LLMs, everything is becoming gated behind logins. Thanks ChatGPT.
