I think that this is a disingenuous use of the (legacy) term 'Lifetime license'. No-one who hasn't recently been screwed over by a software house like 4K Video Downloader [1] would think that 'lifetime' only covered the current lead version number.
A new term such as 'All version [n] updates included' (or something less clunky) needs to be found. At least one could Google it and understand the proposition, if its meaning was not clear - but 'lifetime license' is massively deceptive.
The fact that every single person that brings this up is met with a form of "we don't see a problem, you're just reading it wrong" is a bad sign for the future of this project.
It is not, because you do get a lifetime license. Of course you don't get free "lifetime updates", but you can keep using the version you have paid for as long as you want.
From the pricing page:
"Enjoy the benefits of our lifetime license and get access to all features and upcoming updates with a one-off payment"
