You said that you struggle to see how these platforms don't provide massive value which is fair from your point of view but I personally struggle to see how any of the platforms provide 5€/month worth of value, let alone 10 or 20.
I guess it's a matter of perspective and what do we find valuable in life.
As for tipping, that's a can of worms I'm not going to open because as a european I find the whole concept insane.
