Your misleading people for political purposes. By the way, companies have been getting successfully sued for abusing monopoly power since the 1800's. There are many Supreme Court precedents over the matter across a wide range of industries including technology (Rambus, Microsoft etc).
I'll go straight to the FTC so that people can see for themselves. Link for everyone else straight from the FTC:

Contrary to myth you don't have to have a 100% monopoly or even 50% to have monopoly power. You don't even need to be in competition with the company to sue them. You simply need to establish that they have significant and durable power over the market - and Amazon has both in spades. You then need to establish that they have abused this power to hurt you or your business.
Courts do not require a literal monopoly before applying rules for single firm conduct; that term is used as shorthand for a firm with significant and durable market power â" that is, the long term ability to raise price or exclude competitors. That is how that term is used here: a "monopolist" is a firm with significant and durable market power. Courts look at the firm's market share, but typically do not find monopoly power if the firm (or a group of firms acting in concert) has less than 50 percent of the sales of a particular product or service within a certain geographic area.
Once Amazon decided to deplatform Parler no one else was willing to risk their wrath by allowing them to use their services. That's a literal demonstration of power over the market. Amazon has worked in concert with others like Google to deplatform an up and coming competitor and that puts them squarely in the in the monopoly category. When you have such a grip on the market that you can convince every single vendor, including the companies own lawyers to abandon them on the same day you have clearly demonstrated your power over the market.

They abused their power to shut down a company for political purposes. Within 24 hours of Trump joining the platform it was shut down. Despite other platforms like twitter running accounts routinely calling for violence, murder, rape and even genocide for years on end. Their claims of concerns of violence fool only the media, on the very day it was shut down 'hang Mike Pence' was allowed to trend. It is patently obvious that this was done for political purposes and no one is going to believe that the timing of Trump joining was a coincidence.
The solution that has been consistent with Supreme Court precedent is to use RAND to force Reasonable And NonDiscriminatory terms on big tech monopolies to end their abuse. It's past time to treat big tech as utility company and enforce equal terms for all and put an end to out of control political censorship.
