Limiting notice period to two months and forcing you to give customers the possibility to terminate at any time is not killing ARR. It might moderately increase churn but even then, unless you are frankly dishonest, not that much.
You still have ARR when your customer can terminate their contract.
Even yearly discount which the article presents as done for are still a thing with the possibility of early exit. You just put a clause indicating that the discount is forfeited if the customer leave before the end of the contrat. Phone companies do that all the time.
I agree the article seemed disingenous and almost felt like it was shady (can you believe the EU lets them cancel in a sane way?!). When I hear ARR, I don't think of an annual contract. ARR is equivalent to MRR*12 and can be a mix of contract types or even utility spend ($ per bytes). I understand that "committed spend" is when a business agrees to pay $XX annually, but that's not defined by ARR.
Sure but if you actually have customers paying the annual fee in one go (instead of 12 monthly payments when they can cancel at anytime) the ARR number will be much more reliable. With MRR12 you're counting people who sign up for a month and quit.
And ARR assumes it's recurring too - it's a metric that (people incorrectly think) shows how good your business is at retaining revenue year-over-year.
If a big proportion of contracts in Y1 get terminated at the end of the 12m period (because, say, the customer forgot to renew) - then the ARR will drop like a rock in Y2.
