This is pure nonsense.
Western governments hate Telegram because until now Telegram didn’t cooperate with Western intelligence services like American social media companies do. Everything on Meta or Google gets fed into NSA, but Telegram has been uncooperative.
This will likely change after Durov’s arrest, but it was nice while it lasted.
They don’t even bother reporting Signal usage, it’s a round off error: https://www.statista.com/statistics/258749/most-popular-global-mobile-messenger-apps/
Telegram has almost 1 billion users, half as many as WhatsApp
Some of my favourite red flags:
Signal’s dependence on Google libraries: https://github.com/signalapp/Signal-Android/issues/9044#issuecomment-535194837
Signal dev bullshitting a non-answer and then hilariously refuting his non-answer: https://github.com/signalapp/Signal-Android/issues/9044#issuecomment-534340623
Signal hiding its serverside source code for many months: https://github.com/signalapp/Signal-Android/issues/11101
You can find many more examples.
The last one about server side code, together with Signal’s funding sources and their obsession with phone numbers code leads me to suspect that Signal is just a honeypot by US intelligence.
