Did you notice every price was a whole number?

Or that this was for business accounts that were already cheap? $1/seat isn’t going to cause a mass migration off the platform.

Or that some of the price hikes were 0%?

Fixating on this lowest price increase is deliberately misleading.

You would also have to go back and calculate price increases over time to compare against inflation over time?

If they charged by the day then (rounding up for your convenience) gets $31/mo, you're missing a trick Redmond ...
