I like that the ACM is opening access to the digital library and probably a lot of smart people crunched a lot of numbers to find a pricing model that might be sustainable.

That said, I find the the new registration fees for #chi2026 quite high, given that publications now have to be paid separately. For me, living in Japan with one potential publication, the participation fee alone would rise from 1000$ to 1350$ within one year. This already includes the reduced price. Next year it'd be 1550$.
