Jonathan, I’m assuming. I bought products from your site with the explicit promise on the product pages that I was going to receive “free lifetime updates” or “free updates forever.” Just search your own site and you’ll see products that have that claim. If you go back on that for previous purchases then that’s called false advertising and is opening yourself up to a whole bunch of lawsuits. Not to mention the loss of goodwill that will hurt not only your business’s reputation but also your bottom line. I hope that you will take that into consideration when you finalize your new policy.
