To add some of the posts here about some peoples issue with a so called "lifetime License"...
I have been battling to get a few softwares that i have used for years, installed onto 2 new computers i am moving to. Its been a pain. Couple, key no longer works, or, will NOT activate due to some activation limit. Apparently, when they state "lifetime" they mean for that install on that computer only. You have to buy a new "lifetime" license for each install. Or play the contact the company game to see if they will can update or de-activate the previous install...assuming the company still exits or even responds to you.
One specific software, USB Safely Remove I bought "lifetime" back in 2010, I can not find the key for anymore. No idea where it went off to. And no online account that i can log into retrieve it. just a "Retrieve you Key" submission page, that says I have no key, but I know for a fact it is wrong.
Contacted the company, and they refuse to send me a working key. And told me the online key retrieval only works for those bought over the new online store, in the last 5yrs. They require first i send them scanned images of my drivers license and a utility bill with my matching address on it to "verify that I am the one that bought the software". WTF?? How would that even prove anything...all I gave them when i bought the thing in the first place is basic info, and cc number...how would having a picture id prove anything??? Fine...screw them. I'll pirate their software.
Point is....Lifetime option, can very easily be far more open to screwing over the customer/user.
You pay once, there is zero legal obligation for the company to actuly provide support, updates, or bug fixes, or to allow activations much later on, to what you have just bought. They can put whatever fine print clauses in the purchse/license agreements that you of cource agree to when you buy. Or the "we can make any changes to this at anytime with out notice" clause. Even terminate said lifetime license.
Example, Malwarebytes. I used to work for a technology and repair retail store(MicroCenter) and was officially partnered with Malwarebytes even, and I sold many hundreds+ of Lifetime Malwarebytes licenses to customers, even bought them for my self and family members. The company later fully revoked and discontinued that license and all existing and active ones in 2014. The amount of angry calls we got of pissed of customers now saying their "lifetime" pay one, never pay again software,. was now asking them to pay for it...and they demanded we pay for it, since we(the major big box tech store) sold it to them.
You pay per month, ongoing, the company much more has a legal obligation and incentive to actuly keep you as a customer and improve upon their product.
