The entire web?
Which market is Google unfairly benefiting/profiting in, by leveraging its market share in search?
All of Google myriad of properties benefit from being able to limit competitors web page size, limit their technology use, restrict advertising and gating them behind your own servers.
Plus on top, Google doesn't have to do any of that shit themselves and can gleefully put themselves at the top of every search (and are doing with an ever expanding array of search terms).
As well as increasing the cost of developing a site to compete with any of Google's myriad properties, by having to support HTML and Google's proprietary AMP, that they're pretending is an open standard but is completely under their control.
