God forbid people "suffer" by watching a completely voluntary video of someone trying to help others. Look, I didn't watch the video, but no matter how long it was it's got supposedly helpful information in it and we should be thankful someone's taking the time to post at all.
It's not their job to put it in a format you like, just move on and don't be an entitled ass about it. I'm sure your parents taught you if you have nothing nice to say, don't say anything at all.

It's more that Vivaldi is just Chrome under the hood.
