Is Telegram really that bad and should i look more into it or is sticking to signal really the best option?
Telegram is legitimately bad, it’s only saving grace being that it is STILL BETTER THAN DISCORD! It’s main “Sin” is rolling it’s own Encryption Algorithm; which has been proven to be less than 100% airtight and secure.
Sadly your average user does not care about privacy above all else. They only care about privacy in as much as it can factually and emotionally affect their daily lives. TL;DR: You have to incentivize them to care, and they will often refuse to move, or outright dislike a platform, if a specific feature they love or depend on doesn’t exist, even when it is 100% not critical to the application’s function.
Telegram is closed source on the server side. I don’t trust it. Lots of better options:

We have a website too https://www.privacyguides.org/en/real-time-communication which has decisions based on a privacy and security related context.
One of the main requirements there is that recommended instant messengers undergo auditing.
