Sure, you can say that you aren't "required" to tip in these cases, or that they're taking advantage of tourists who don't know better, but still, they're asking for a tip. To me, "no tipping culture" means that tipping simply does not exist. Europe has a tipping culture; it's just different than the US's.
I haven't seen it in this form in France (yet?). But I do see more and more payment terminals that are asking for a tip when they're presented to you. The amounts usually seem fixed, and you have the option of picking 0. I've mostly seen this in bars and similar situations.
Some stores may also ask you to "round up" to give to some charity. Fun fact: these didn't use to work with Apple Pay, so if you said yes, the assistant would have to cancel and restart the payment process.
