No, its like a landlord doing renovations and improvements to keep up with the local property market and then putting rent up to match those improvements and maintain parity with the market. (with notice and options to pay old level for period upfront)
Sort of. You can keep using the product version from when you last paid (the beginning of the sub not the end). So if you were annual then you actually have to downgrade to a 1 year old version. It's a really wonky system. I was pretty upset when they switched to it but I love their products enough that I gave in.
More like a landlord doing renovation, feeling the budget crunch, and looking at the calendar and realizing "Oops! I forgot to raise rent in the past 7 years!"
The price increase they're asking for is approximately equal to inflation from 2015-2021. They don't even try to include the last year's inflation.
