Hello everyone.
I make this post because recently I noticed that the thumbnail of some of the videos, that I uploaded to DTube have gotten replaced.
I have been moving from Youtube to DTube in the hope of preventing censorship. For reference take a look at my DTube profile: https://dtube.video/c/andersrh
As you can see the thumbnail for the Avicii video has been replaced with a NSFW (Not Safe For Work) image. In my opinion this does not encourage free speech.
The real thumbnail should be this one, because it tells about the symbolism in the music video of the Avicii song:
I make this post to warn you that some day DTube could be censored just like Youtube is today, so I begin to doubt it could be an great alternative. I fully understand that the Steem blockchain - just like Bitcoin is secure - but what about IPFS which hosts alle the videos and thumbnails?
Take a look at this one: 
Especially this comment:
Data on IPFS is not permanent - it is a bit like torrents. I want a platform where law enforcement cannot take down my content - and DTube is not that.
