I'm no expert, but it's not just that they dominate the search market, it's that they use that position in less than ideal ways. For example, Google Snippets takes away valuable traffic from sites. Google has also been accused of prioritizing their own results over competitors.

You're conflating topics. I'm saying the cost of switching is trivially low for search engines. The moment Bing becomes better I can switch to it with a "single click". The moment I like something about Android or iOS I can't switch with a "single click".

Whether or not a search engine should be barred from showing snippets is a different topic IMO.
