Considering the last price increase was almost 4 years before this one goes into effect, most of those are pretty modest 1-4%/year increases. In line with inflation. The notable outliers are F1 and F3 which got a lot more expensive
Apparently F1 and F3 are "Office 365 for Frontline Workers". F3 is kind of like Office 365 Basic, F1 is stripped down to mostly read-only access plus Microsoft Teams
A 5% increase is still a sizable when you consider the number of licenses that even an SMB may have. I don't deal with our MS licensing directly at $DAYJOB, but we've got something like 1300+ employees most (all?) of whom have M365 E5 licenses, that adds up to (roughly) an extra $4K/mo or $48K/yr when it comes time to renew our annual licensing.
Is it going to break the bank and send us into a financial death spiral? Absolutely not. But, you get enough companies deciding to jack up pricing at around the same time and it comes out to a significant increase in our lights-on budget - death by a million cuts hurts just as much as Broadcom raking us over the coals with VMWare license increases.
5% is 5%. If you have more employees, you also presumably have more revenue. That's why percentages rather than absolutes are the right metric. And keeping up with inflation isn't "jacking up pricing".
