I agree, except the DMA specifically only applies to companies over a specific size. I think if the German newspapers were at FB/Apple scale, in terms of number of users, then the DMA would apply (i.e. they would be designated gatekeepers or similar) and they could also be fined. Although I think pay for no ads is also a violation of GDPR maybe?
Surely there is a middle ground where its at least possible to install apps that apple haven't approved[1]? I also like the idea of the _higher_ bar that the app store is supposed to have (not that this bar is always met), but the lack of any alternative is really crappy.
I don't think any current flow in the water is deliberate. The heating comes from the resistive heating of the coil. The issue (i think) is the coil being uninsulated, allowing some current to leak out through the water, hence the tingling sensation others have mentioned.
