But we're not discussing an item from a physical store? We're discussing software sold online.

Why do you think there is any difference? Did servers and backups and data centers and electricity and cooling and ups batteries and generators and facility operators and banwidth all become free while I wasn't looking?

They're going to need "servers and backups and data centers and electricity and cooling and ups batteries and generators and facility operators and banwidth" regardless, because they're still selling licenses. The cost of providing downloads to existing owners is marginal.

That's the difference between a license and a product my friend

Exactly. OP bought a lifetime license but expects a lifetime product.

If you bought a license from a physical store - depending on the language of that license - yes, it would entitle you.

I bought a Windows license from a university book store. I can download copies of Windows all day if I want.

So what? So MS happens to feel like providing distribution servers. That has no bearing on anyone else.
