Which weapons haven't belonged to a NATO country?
There's a huge difference between continuing to send them defensive weapons, and upping the game to giving them jet aircraft which will be used offensively and which the Russians have warned would be seen as a major escalation.
You can say "fuck the Russians" if you like, but you must accept that this would be a significant escalation which brings NATO into much closer contact with Russia than it currently is.
