My view is to NEVER buy a product with a recurring payment. There is never a guarantee that the product will be improved enough to warrant an additional payment.

Thus, I always consider a recurring payment as the "Lazy developers guide to riches." It's scammy because it requires no marketing. Developers hope and pray you've forgotten so they can continue to ding your credit card full price for no changes or inconsequential changes.

If you want my money, sell me the product at a fixed price. Later, if you can convince me that the new upgrade is really better, I'll happily pay for the upgrade up to 50% of the original purchase price.

My personal policy started with Adobe. I bought and paid for upgrades when warranted for decades. But when they switched to a subscription model, I just used my older versions. Now a company called Affinity has advanced, superior image and publishing software for less than $50 each, and I am thrilled did not buy into Adobe's subscription model.
