Apart from telegram not having any kind of actually used E2E Encryption, they store everything, which means the cost of running their service is crazy high compared to something like whatsapp which AFAIK only stores stuff up to 3 months when the device isn't online. So we have an app which has access to everything you send, and has incredibly high hosting costs with no real income, you put 1 and 1 together and you can see it for yourself. Ironically they claim cloud storage as the reason for not having E2E, yet matrix seems to be able to do just that.
