People go back and forth on this. When they are trying to sound "very smart", they'll insist "well actually, the Russians invaded in 2014!"
But something fundamentally different happened in 2022.
Remember, Zelensky was elected on a platform of negotiating with Russia for the dispossessed territory. That was acceptable 2014 - but certainly not now.

No, I think what you have is mostly different people saying different things, not people going back and forth.

Yes, an escalation in the level of conflict from the Russian side intended to bring a rapid conclusion of the war happened in 2022.
