Honestly it would be better if Telegram dropped the facade of having E2EE. It's generally very low on the priority list of most people anyway, as much as it would hurt anyone reading this, but that's the truth. People are not using it for secure messaging, but for a better UX and reliability.
EDIT: Telegram does require a phone number to sign up.
Do they still not require ID when you buy a SIM card in Ukraine?
You can just grab any prepaid SIM and use it if that's your style
That said, such high-tech operation is just a geeks fantasy about spies. When you cross the line where it becomes reality, you’re either a very big name with a sudden drug/rape history or a subject for waterboarding which is the most effective cryptoanalysis tool invented.
Yes, burner sims definitely help evade investigations, but they are harder to get nowadays, depending on jurisdiction. For instance you can't pay cash for a SIM in North America. It has to be a credit card or a bank transfer and that's a form of ID.
I was using telegram for one single usage, which was a group organizing local meetups events for expats. When I switched smartphone I really didn't want to install an app just for one group and would have preferred using telegram web to consult it occasionnally. Every time I tried logging in on a computer/smartphone it told me to validate the login from telegram on my original, now wiped clean, smartphone. I just gave up.
Then why is a phone number needed to register? If PII is "not shown to anyone in any way" then it should be completely unecessary to provide it to the service. Do not let that particular wool be pulled over your eyes.
It's only on HN I ever see people set up Telegram as some supposed uber-secure private app for Tor users and then demolish that strawman gleefully.
Also, people tend to state they have nothing to hide, when they feel they have nothing to fight with. But I can't count the number of times I've seen a stranger next to me on a bus cover their chat the second I sit next to them. Me, a complete random person with no interest in their life is a threat to them.
I just did it to gather anecdotal evidence and the answer was, the founder is in jail to protect their privacy.
Christo Grozev shared screenshots of a few CSAM channels yesterday, but if you search for them, they do not seem to exist.
Telegram clearly does less pre-moderation than Facebook, but they are smaller and have less computing and they do not seem to rely on the masses of Nigerian moderators that work for 5$/day as Facebook does.
My speculation is that he set a too high price to share the private data with france or USA.
Today, on the same topic, another tech site which generally gets a lot of things right (but whoever is responsible for writing about Telegram, or maybe their internal KB, is consistently wrong and doesn't care about feedback) wrote that it is an encrypted chats service: https://tweakers.net/nieuws/225750/ceo-en-oprichter-telegram... ("versleutelde-chatdienst" means that for those fact checking at home)
The average person I know that uses Telegram ("non-techie" as GP comment put it) certainly doesn't. People join telegram because it has a group they want to join, or via word-of-mouth of a friend recommending it. Normal people don't read tech news, and if they do they don't give it much weight.
Maybe that sucks, maybe they'd be better off somehow if they did, but the reality is that most people live in a different universe from those of us who care about e2ee security or read tech news with interest.
the perceived secure nature of telegram has been memorialized in mainstream rap, courtesy kendrick lamar in 2017 (https://genius.com/11665524).
There is so much misinformation around telegram that alone made me trust it more (if a known liar tries to discredit something, it increases chances of it being good--it is about comments here on HN).
