Over-charged relative to what? What is the objective criterion by which you know you are being "over-charged"?
* I bought LR 2.5 half a years ago for 75€ as an upgrade which makes 2€ per month this far.
* I
rarely use PS-type of application, but just to get me covered I got Affinity Photo for 40€.

For me personally, I don't feel the CC updates have been influential (useful on occasions yes), even more so after that long delay for the current major release, I'm rather disappointed (not taking into account there is no more perpetual licence). Moreover, this last update matches my personal idea of what happens when there is no intent to upgrade as the money just flows in. Keep it enough (barely) up to date is what I perceive. I was one of those who never had any speed issues and that is apparently the biggest feature for the new release, with the addition of range filter. The CC updates in between I don't care of.
I'm having no issues people liking subscription and especially from businesses perspective that seems like a good deal.
While I have got paid from time to time, photography is only a hobby and sometimes longer breaks happen.
Another monthly bill on top of other bills is not that minor after all in total, considering that would not have been a priority payment.
Anyway, good luck for those with the subscription.
