You would think that someone at Proton would've had the foresight to realise the reputational damage this (along with the LLM announcement) would do to the company.
Without wanting to sound smart after the fact, I've been suspicious about Proton for years. I briefly had an email account with them but I could never quite shake the feeling there is something off about the whole company. This move just confirms to me I was correct to be suspicious.
A few little things rather than one or two big things - email advertised as private but they won't let you use anonymous addresses (like anonaddy or duck.com) for recovery addresses, an ever growing portfolio of products that seem unfinished or incomplete or lacking in standard features like they're trying to corner the whole privacy market rather than making one or two products but making them really good, poor customer service and support as a continual theme throughout their existence.
To be clear, I'm not suggesting they're doing anything dodgy, I just feel that I don't really trust them. They just make really odd choices and it all feels like a haphazard rush.
