No, it says expired.
Your right to receive updates is limited to the time that you selected when you ordered FileZilla Pro.
If you have, infact, ordered a "Perpetual License", then you would have agreed to the Terms and Conditions when ordering FileZilla (here's a random old copy: https://web.archive.org/web/20211128083132/https://store.fil...)
It clearly says in the T&C that you agreed to:
> All risk of loss for the Products shall pass to You upon delivery of the Products to the location specified in Your Order (even if no signature is required for delivery). For the avoidance of doubt, the delivery of downloaded Products occurs when the Products are downloaded.
FileZilla's Terms and Conditions are a mess. https://filezillapro.com/terms-and-conditions/
It does say:
> In a one-off purchase you will have a right to receive services or other rights for the maximum period of time indicated in the package you have purchased or ‒ missing that indication ‒ for up to five years.
It also says:
> Unless registered, your copy will not receive updates and will not exploit the services of the Software.
So, I would assume that if you purchased the Lifetime license, and you registered the software within the 4 required weeks, then they are infact breaking their contract with you.
Which is a bad thing, and it's good to warn people about that clause loudly.
The lifetime license purchased today is not a perpetual license. FileZilla says that it will update it for life.
So, respectfully, no, it's not good to warn people about the clause, because people purchasing the product today do not run into this issue.
If Microsoft blocked me from installing an obsolete version of windows via the activation servers, it would be reasonable to hold that against them.
It's not about updates, it's about being able to use the original purchase.
