Fair enough, but then it's the same issue to try and convince them to add you on WhatsApp (or iMessage) if they use Telegram. The point is that these are all platforms that we similarly end up stuck on, depending on what most people in our community landed on. In that way it's not so different to the situation in the US.
People only want to use one messaging client for all their contacts, and as long as the clients remain closed platforms, we are prevented from just using whichever client we individually prefer, we have to use the platform decided on by the community, or fight an uphill battle to get everyone to reluctantly install a second messaging app just for us.
I moved from Google Search to Kagi, and I really like it. It's a bit expensive though the experience is really nice, and you know where you stand with them as a customer, regarding their priorities/motivations.
