Heavily means the key is large so it takes longer to crack, but also longer to encrypt/decrypt, so the service is more costly to run and slower. At least I've seen it used that way
In this context "heavily" means "we can't legally claim it's end-to-end encrypted because it's not".
Also it's not even post quantum, so it's not heavy. Telegram's Diffie-Hellman breaks instantly with a quantum computer large enough to run Shor against it.
Also, the keys sit on the servers' RAM, no matter what they lie. There is no global distributed RAM system, especially one that encrypts data in distributed fashion and works at the negligible latencies that Telegram boasts.
I've never claimed that anything about telegram's encryption is "heavy", because I don't even know what they use, I just said what "heavy" usually means
> In this context
In this context it's marketing bs for people that only seen action movies where hackers quickly cracked encryption. I'm sure whatever telegram uses is not that ridiculously easy to crack
