@ShadSterling This claim is absolutely false and a complete misunderstanding of their TOS. Their snippet that "by using Firefox you grant Mozilla a royalty-free nonexclusive world-wide license to improve your experience" does NOT grant them rights over your content!
This is generic legal boilerplate for "if you use Firefox, we can legally be allowed to let you interact with the browser and we can use your content (locally) to personalize your experience".
This exact boilerplate can and most likely applies to every instance of Fedi under the sun, and every service or application you've ever interacted, and will ever interact with.
@alextecplayz uploading data to a site and through an app are very different things; the terms grant Mozilla rights to posts you enter on a techhub.social page, even if it’s a private message, even though the app should be able to do that without Mozilla ever having a copy of the data. Mozilla can’t need rights to data it never has, but they’re requiring you to grant them anyway.
@ShadSterling This is again a misunderstanding of the legal language. Mozilla doesn't want useless, unnecessary lawsuits, so they're covering their ass with this.
They do not have access to such data, but in the event that someone sues them for it regardless, Mozilla can point to this and their privacy policy to outline what the browser collects and stores on-device, or what is collected and transmitted to Mozilla (e.g. analytics).
The license is required to ensure that Mozilla can legally process and transmit data entered by users through Firefox, even if it does not collect or retain that data. Simple as that.
