Monica raises a very valid point.
The World Wide Web Consortium (W3C) is the organisation which writes the standards on web design.
The Equalities Act 2010 requires that organisations must make 'reasonable adjustments' to make sure their services are accessible. This is so that people with disabilities are not excluded because of their impairment.
Pause, Stop, Hide is the standard which applies here:
Moving, blinking, scrolling
For any moving, blinking or scrolling information that (1) starts automatically, (2) lasts more than five seconds, and (3) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it unless the movement, blinking, or scrolling is part of an activity where it is essential;
and
Auto-updating
For any auto-updating information that (1) starts automatically and (2) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it or to control the frequency of the update unless the auto-updating is part of an activity where it is essential.

Ad blockers are the obvious answer but if you find these are not effective and there is no mechanism to pause, stop or hide these videos then the developers who have made these changes are not applying the standards required by the Equalities Act 2010 and you have a right to make a case that they remove them.
What were your dream names for your kids when you were growing up?
