@belle I found your post very interesting. The point about lack of Android support is very salient. I haven’t been on here long enough to speak on diversity.
Obviously I don’t speak for @manton, but as a user, for me it comes down to the terms of service. On Twitter for example the TOS state:
By submitting, posting or displaying Content on or through the Services, you grant us a worldwide, non-exclusive, royalty-free license (with the right to sublicense) to use, copy, reproduce, process, adapt, modify, publish, transmit, display and distribute such Content in any and all media or distribution methods (now known or later developed).
You’ll find similar clauses on the Instagram TOS. In short, you “own” the content but grant licenses for the service to do whatever they want with it. Compare that to Micro.blog’s TOS:
Content. Micro.blog does not claim any ownership rights in any text, images, photos, video, sounds, links, works of authorship, or any other materials that you post to the Service (collectively, “Your Content”). After posting Your Content to the Service, you continue to retain all ownership rights in Your Content, and subject to any licenses granted by you, you continue to have the right to use Your Content in any way you choose. By posting or sharing Your Content, you grant Micro.blog only the limited rights that are reasonably necessary for us to provide the Service, which includes, without limitation, the right to store Your Content and share or display it with other users of the Service.
You are not granting licenses to M.b to use your content.
I understand that the best way to fully own your content is to host it yourself on your own server but many of us can’t or won’t do that. In that case, entering into an agreement where I retain ownership of the content without granting license is the best that’s available to me.
