I'm curious about the interplay of two items from their FAQ:
> 10. What if I do not renew my subscription?
If subscriptions are not renewed, you will lose access to the software on the day that a new subscription should have started. Please note that the software will stop working if not renewed.
> 13. I have an IDA perpetual license, when do I have to change to a subscription?
At the end of your current support period all renewals will be moved to the subscription model. We are offering our existing users an opportunity to pay only your current renewal price for your first year on the subscription plan.
So maybe I'm mistaken, but it sounds like they're trying to renege on perpetual licenses?
> 14. What if I don’t renew on the subscription plan?
Existing users can continue to use the version of IDA Pro/Decompiler he have purchased under the perpetual license model indefinitely. However, they will not be able to receive product updates and tech support after the 12-month support expires. No re-downloads of past versions will be provided, so make sure to keep all necessary backups.
