The data allowance from my service provider is so low that I rarely load images, browse without JavaScript as much as possible. I've also configured my browser to not download embedded fonts. The web has gotten so incredibly bloated since it's inception. If I could have 3 superpowers, at the top of the list would be the super power to force at least web developers to have to read out loud every single byte of every page they ever browse regardless if it is a site they are developing or just a site they are visiting for entertainment. This would include not just the html, css, javascript, but also a hexadecimal representation of every image, icon, pdf, audio, video and any other bit of data that constitutes a web experience. I may exempt them from reading of things such as operating system updates or desktop executable programs. If that didn't lead to the web becoming less bloated, I'd use my superpower to require them to read it all in binary. Of course since the reading would be required to be done out loud it may annoy their spouse or children or others. In case of any annoyance, they would be required to either cease their browsing session, seclude themselves so as to not annoy others, or transcribe with paper and pencil every byte that would have been read out loud.

Oh, yeah embedded videos......
......well I do my best to never even be aware of the existence of embedded videos by configuring my browser to never load them. I still have work to do on that because occasionally some slip by. This is the case even when I am at a WiFi hotspot with unlimited high speed internet access.
YouTube has a special place in my /etc/hosts file so it doesn't waste my bandwidth.
As for videos that are an integral part of the initial post, I almost never watch them. If there is a video I think I really need to watch, it gets bookmarked into a folder to stuff to watch when I get to a WiFi hotspot.
More often than not I find that videos are a waste of time to watch due to the fact that the necessary data could have much more efficiently been conveyed through a plain text document possibly with a few images. There are rare occasions that a video may equal or exceed the efficiency of conveying an idea accomplished by a text document with images. Numerous videos are very poorly made and they are filled with uhms and other filler words, they don't get right to the point. If you are making a video to tell me a recipe for insect repellent...DON'T!! and for the love of all that is holy, don't make that video promising a non-toxic insect repellent recipe and take 18 minutes discussing DEET and how bad it is!! JUST type up a text file with the ingredients and any mixing instructions and be done with it! If you want to make a video of how to paint a mountain scene then that may be something that would be more difficult for someone to learn by reading a text file with or without pictures so a video may be appropriate. In most cases, if you want to make a high quality worthwhile video, you need to invest quite a lot of time into it. In most cases, you should start with writing a script and then proofreading that script and then rehearsing and then doing as many takes as necessary to get it right, doing any necessary editing.
