Maybe the founders can’t sell out anymore, but looking at what Raspberrypi just did the company can still end up partially on the stock market.
It’s a bit different because of the stated values though.
Raspberry pi’s foundation is focused on making computers available broadly, while this new organization is focused on making privacy widely accessible.
While both can be commercialized, the pi’s foundation has no fundamental problems with selling out privacy or focusing on money to achieve those goals. Proton would have a much harder time arguing that profiting from sale.of private data supports privacy.
This is relevant because it means even if the remaining shares end up on the stock market, the foundation can use its majority ownership to veto any privacy concerns.
Time will tell. I could also have missed something
