But I have multiple choices for email, search, video hosting and browsers. I don’t have any choice for water, electricity, sewer, on any other public utility. I am sure there are a bunch of people on here that don’t use any Google products and are using DuckDuckGo, Firefox, ProtonMail, Vimeo. There are many choices.
Not video hosting you don't. If you want to build a significant English speaking audience, your only real choice is YouTube, because that's where people search from. Seriously, who has a "Vimeo" app on their phone? On their set-top box?
Same thing if you want to watch interesting videos: most of the content is on YouTube.
