Yeah, I was talking about retroactive changes of course (and not changes for future versions).

Their founder/CTO (who seems to be MIA these days) published this back in 2019:

https://blog.unity.com/news/updated-terms-of-service-and-com...

"For this reason, we now allow users to continue to use the TOS for the same major (year-based) version number, including Long Term Stable (LTS) builds that you are using in your project."

Which is something they presumably "forgot" about...

yea, they did "forget" it. It's because this condition is _not_ in the TOS! It's a side-channel communication/agreement.

The unreal terms[1]:

> 7. The Agreement Between You and Epic

> a. Amendments

> If we make changes to this Agreement, you are not required to accept the amended Agreement, and this Agreement will continue to govern your use of any Licensed Technology you already have access to.

vs the unity terms[2]:

> 23.2 Changes to Terms

> To the maximum extent permitted by applicable law, Unity reserves the right from time to time to (and you acknowledge that Unity may) modify these Terms (including, for the avoidance of doubt, the Additional Terms) without prior notice.

I never implied it was otherwise.

However if we look at their TOS from 2019 (the time of this blog post) they do have this:

> if the Updated Terms adversely impact your rights, you may elect to continue to use any current-year versions of the Unity Software (e.g., 2018.x and 2018.y and any Long Term Supported (LTS) versions for that current-year release) according to the terms that applied just prior to the Updated Terms (the “Prior Terms”). The Updated Terms will then not apply to your use of those current-year versions unless and until you update to a subsequent year version of the Unity Software (e.g. from 2019.4 to 2020.1)

I don't think the section is still there anymore? But presumably it still applies to you if you haven't upgraded past 2018/2019 versions. But it was actually in the TOS (just like for Unreal) which I didn't expect.
