Big tech needs far stricter regulations but I don't think people would like the internet very much if Google was forced to sell off services like YouTube. Nobody else is offering unlimited free hosting, discoverability, promotion, and bandwidth for video content and nobody ever will again. If the chromium project was sold off to some other shitty tech company, do you really think they'd keep the open source 'ungoogled' version readily available for everyone? A Google breakup would just mean that other tech companies like Apple, Microsoft, Oracle, etc get more powerful.
If there's an appetite for breakups why not start with the companies that control our food and news
