YouTube can delete channels that aren't "commercially viable"

YouTube has been under scrutiny for several years now with regards to how it approaches content creators, including issues like copyright strikes, and now many creators have pointed out an alarming paragraph in their new terms of service that reads as follows:

"YouTube may terminate your access, or your Google account's access to all or part of the Service if YouTube believes, in its sole discretion, that provision of the Service to you is no longer commercially viable."

All over social media on places like Twitter people are not only questioning how sinister this sounds for creators, but also the lack of clarity around the meaning of "commercially viable".

December 10 is the date that these terms of service go into effect, and already people are worried about what this bit in particular will mean for YouTubers, especially those who are demonetised. Below is another paragraph on how this process will happen:

"We will notify you with the reason for termination or suspension by YouTube unless we reasonably believe that to do so: (a) would violate the law or the direction of a legal enforcement authority, or would otherwise risk legal liability for YouTube or our Affiliates; (b) would compromise an investigation or the integrity or operation of the Service; or (c) would cause harm to any user, other third party, YouTube or our Affiliates. Where YouTube is terminating your access for Service changes, where reasonably possible, you will be provided with sufficient time to export your Content from the Service."

What could this mean moving forward?
