Hi Sven, thanks for the engagement. Going by your post stating that you have an "average income," seeing on your profile that you are a father, and additionally seeing how you describe your own podcast as "shitty," I take it that your podcast is not how you pay your bills or provide for your family, and that you have another source of income.
This may come as a total surprise to you Sven, but some people out here do not contribute to the bitcoin space as a hobby, but as a full time job – which includes taking a massive amount of risk, which you, again going by your own statements, do not appear to have been willing to take. No shame in that, but maybe a good time to check your privilege and see whether that really puts you in a position to judge those who have.
I, and I am sure many other creators you are referencing in your post here, actually live off of bitcoin; Zaps are not some fun way to boost engagement for us, but another way to pay our bills. Contrary to you, we support the bitcoin ecosystem and services/projects we find valuable every time we spend our money, not by sending someone 2 cents on a tipping protocol.
You're free to disagree with that, but I hope it helps you understand where many of the creators you are referencing here are likely coming from.
