You can't brag about your open source server code and then stop updating it for a year.
You can't spend all day on twitter writing bullshit to attract a certain political demographic and then add a crypto wallet to a chat client.
etc etc
The tech community is seriously guilty of letting perfect be the enemy of good.
For the record, I'm not a huge fan of the crypto wallet thing at all but I just don't use it.
You just used "closed server source code" as an argument against telegram? I also agree that it doesn't matter at all. But then why trashtalk telegram?
Why not, if it solves payments between Signal users (believe the Signal-MobileCoin integration, disregarding Moxie's involvement in both for a second, is a direct response to the now-defunct Libra/Deim)? Personally, I see MobileCoin / wallets as a genuine path to monetization for the Signal Foundation. Though, it remains to be seen if it is any successful.
