That was largely gut-level analysis for my personal decision-making but here are a few of the things I considered:

1. Value proposition in the context of acquisition, featuring a heavily-marketed privacy brand and a base of privacy-conscious users (harder to profile, more expensive data)
2. Obfuscation of funding sources via ‘venture philanthropy’ non-profit (a la OpenAI) housing closed-doors for-profit operations
3. Rapid expansion to full-coverage consumer productivity cloud platform alternatives (vpn, mail, drive, calendar, wallet, passwords, etc)
4. Weird pattern of being blocked then let through without future contest by numerous data-hungry entities including thiel, and generally just allowed in a few too many privacy-unfriendly places for my taste
5. And the usual reservations re: privatized privacy and commercial OSS

Again sorry that’s all hand-wavy. Probably shouldn’t have thrown shade without something more concrete.
