While I agree that they are very wide, and this is anti-user, those terms seem pretty standard in the industry. No need to single out grammarly.

[Highlight by me]

Apple: https://www.apple.com/legal/internet-services/itunes/us/term...

> Our Services may allow you to submit materials such as comments, pictures, videos, and podcasts (including associated metadata and artwork). [...] You hereby grant Apple a worldwide, royalty-free, perpetual, nonexclusive license to use the materials you submit within the Services and related marketing, and Apple internal purposes. Apple may monitor and decide to remove or edit any submitted material.

Github seems to be the only one I looked at which actually lists something they are not allowed to do: https://help.github.com/en/github/site-policy/github-terms-o...

> We need the legal right to do things like host Your Content, publish it, and share it. You grant us and our legal successors the right to store, parse, and display Your Content, and make incidental copies as necessary to render the Website and provide the Service. This includes the right to do things like copy it to our database and make backups; show it to you and other users; parse it into a search index or otherwise analyze it on our servers; share it with other users; and perform it, in case Your Content is something like music or video.

> This license does not grant GitHub the right to sell Your Content or otherwise distribute or use it outside of our provision of the Service.
