I mentioned this in a TWIP podcast before, but no content creator should be trusted blindly 100%. Privacy Guides should never be trusted 100% as well.
At the end of the day, content creators have their own views. There is nothing wrong with hosting opinions, but projecting them as an objective truth is dangerous.
Perhaps THO was irked after being ghosted by Proton, which reinforced his growing doubts about the Proton ecosystem. There are a lot of people who agree with him, and for valid reasons! Like, would you trust any company with your data just because they said so? I even unsubscribed from Proton Unlimited for this very reason.
So if that’s a completely valid take, why am I even typing this? Well, not everyone has the money to self-host or pay for multiple services. Proton being an ecosystem is a benefit for the average person, but not particularly great for high-risk threat models.
While I’m sure that he doesn’t have ill intentions, there is growing trend of content creators going after privacy-friendly solutions because they don’t go far enough. Which ironically ends up harming a lot of people. (not saying that THO is doing this for the record)
TLDR; THO has valid opinions, but reconsider whether your situation would actually fit what he suggests is the optimal choice for your privacy journey.
