If this is the same person I think it is, I would take their comments with a huge pile of salt. Not saying they're wrong, but...
A couple years ago this Linux-Is-Best dipshit somehow got onboarded as a mod of the /r/massachusetts subreddit, started banning a ton of users for pretty unreasonable reasons, brought a few other seemingly random moderators on board and almost nuked it out of existence by being an unhinged little weirdo. They claimed to have worked at Facebook/Meta and I forget which, but they were found out either to have made it up or they were just a bottom tier content moderation employee.
You can go find some posts about it, but this person's not well at all even if you happen to agree with them. If this is the same person. They're not trust worthy. Privacy's important, big companies are creepy, do what you can to protect yourself and use linux if that's what gets you there, but again I would take anything this dipshit says with a grain of salt.
