thing is corporations or large companies will always exist since certain services need a lot of cooperation and infrastructure to exist. for example no one person can produce an entire computer on the number/scale demanded by the economy, and everyone working separately would only reduce availability and create redundant optimizations and management as each tries to compete alone
i know this is a bit extreme of an example, but its for things like this, like water and electric and tv and internet services, that large companies exist. there is no way to make it easier for people to get into said market and compete since the initial capital they would need to make their service big enough to compete is too high, esp when companies like AT&T have existed for decades and reinvested their profits into improving or expanding their services. the only way to ensure these companies dont forget people over is regulation
deregulating smaller businesses carries the risk of local monopolies and business abuse becoming a problem, but i agree that they should only have the absolute minimum requirements like min wage and working conditions. and regarding companies on the internet, the dot com bubble should be enough clarification that even there some regulation is needed
