It's infuriatingly dumb as my backup high street banks (in multiple countries) have failed to implement this, I noticed when I got a new eco card, it's not even always 150 eur or 5 times, sometimes it is less of both.
I understand risk mitigation but I am not a moron and it's my responsibility if my card is used without my authorization and thus they can just pass liability onto me I don't care, it's not a credit card I can't spend more than I have on it.
Secondary to that, at least here they never update contactless limits, so it's still 500kc/20 eur, ať which point you are required to enter pin anyway, iirc back home in the UK many terminals allow up to 100 per transaction without pin
