I don't think the Telegram concerns are just privacy. I've read some mild speculation in other comments that the app may be compromised. 2FA will not protect you against a compromised app.
Thanks. I see their hair now. But I still don't see anything between thier shoulders and their hair. Except what looks like a banana with a frilly collar.
I think the major hurdle is that they can't just rebrand the existing app, they have to release a new one. Keeping the K-9 app around will help the user transition long term. The folks in this thread follow Thunderbird and Thunderbird for Android development but my guess is the majority of K-9 users don't. At some point when or if K-9 installs drop they will probably revisit the issue.
Sidenote: I remember a PSA/campaign that had people flashing the 👌 gang sign at each other. I don't think it was Do The Right Thing. I think it was about being a good person in your community like helping people carry their groceries home but I've never been able to find out what it was. Any chance you recall?
Is this the new Australia Day?
