Otherwise, I usually prefer free open source solutions (FDroid), but I regularly donate to keep the projects alive. 1 and 2 are small dev studios that I am happy to support.
Just wanted to add that it's a music sequencing/composition/recording tool. I also bought it some 20 years ago and they really delivered the lifetime free upgrade thing - bought some upgrades and plug-in packs now and then nonetheless - - great tool. I feel that presently, I use roughly 20% of its features, but I never find the time to dig deeper.
edit: refering to the Desktop version
I could provide a low-effort option...

love the hat and also the grumpy face for the tech-duck (seemingly, you beat me to the idea)
What do you recommend?
If Signal was not simple, my family and friends would likely use Telegram or WhatsApp. Even switching to Signal required a number of (general) newspaper articles criticising the status quo. It's likely not optimal, but okayish and sharing opinions and holiday impressions feels a bit better.
Switching a service is a slow, difficult process and many contacts will not follow, given they would abandon other contacts among friends, family, parents at school, sports teams, ... (now, I'm here, using 4+ solutions).
If training or even curiosity for the technical process is required, very few people will follow. If it takes me (with strong IT background) more than 30 minutes to understand/implement, I may have a decent private solution, but I will feel quite lonely soon.
