The big three producers refusal to expand will hurt them a lot, chinese producers like cxmt got a great way in and have already started producing dram that works for ddr5 6000mhz.

Proton are building a walled garden though. Trying to export and migrate from it is hell. I much rather have common imap/smtp and setting up pgp keys myself. That way I can easily import my local backup to a new provider if the need rises.
