I live in the UK and have no idea what 'recent street harassment ban in UK' refers to.
Talking to strangers is not 'impolite'[1], let alone 'border line illegal', in the UK.
[1]Depends on context of course. No chit-chat in public toilets, thanks.

So yes, then?
Border line means there are many variables, individial feelings and so on. In UK this interaction may be criminal with recent updates. Law is very vague and wide open to interpretation.
Consider this:
* it is illegal to block someones path, law is very specific about that
* is sniffing or even licking someones cooch normal? I can ensure you, many people have VERY strong feelings about that! For some others it is normal behavior!
* is commenting on apperance, clothing etc.. acceptable? Law is very vague
OP is using the usual conservative tactic of conflating "person convicted of catcalling, stalking or other intentionally sexual behaviour" with "person talking to a woman".
1) Compared to the US, Brits live very socially isolated lives. You are just used to it.
2) There was a (small) government taskforce in the UK to prevent/arrest men for approaching women on the street. It backfired badly as you might expect. It was politically unpopular, yet it got enough coverage to change people's behavior but not in the way the politicians expected. Specially, amounts of SA didn't change but the number of dates did.
3) Someone is upset at this change in behavior and is trying to revert it.
4) This is someone from the leopards eating faces party complaining about having their face eaten by a leopard.
