In the case of the web, it’s also bad for any single company to have as much influence as Google has on web standards development. There’s simply too much conflict of interest at play. As a web engine developer they should have some amount of sway but if any party is to have disproportionate power it’d be better if it were an org like Mozilla that’s more likely to give issues like privacy and potential for abuse greater consideration.
It was just funny reading an American suggesting that a monopoly in the browser space would be bad ;)
Also, as a European, I can also say that a monopoly in the social media space would be bad but there is always TikTok or are they French?!? /s
My new phone is full of many more libre apps than my old phone.
