Companies are just groups of people. Why should a group of 100 people get taxed more than a group of 100,000 people? Progressive rates on wages make sense because it's applied to each person individually.
The legal definition is certainly not "groups of people." Describing them in this folksy way is outright misleading.
It would be the other way around. This is in order to encourage the formation of new groups, which almost always start out small.
If that's your goal, having slightly lower taxes is a terrible way of doing so. It's far better to address the barriers to business formation directly (eg. availability of capital, market power of incumbents, regulatory requirements). We want people to found new companies to produce a better product (eg. Tesla), not to chase some tax incentive.
Or tax on revenue once company becomes big enough. Taxing on income made sense to make investing into expansion a good thing, but those companies clearly don't need to be bigger, it seems to just make stuff worse and worse.
That would cover most professional services firms (eg. lawyers/accountants). I don't really see why they should be considered worse than a mcdonalds.

TSMC brings in 73.67 billion/year in revenue. Equifax only brings in 5.12 billion/year. Which one is making stuff "worse and worse"? Surely there's a better metric than dollar amounts, which totally ignore the financial nature of the underlying industry?
In some businesses there is also a benefit in scale (like in trading), and there you see the US banks leading because they've had it.
If you want the US banks to fully take over IB and corporate banking, definitely do tax the EU banks painfully more.
Or tax every financial counterpart painfully more, so then eventually the customers pay much more for their loans because the financial system has become so expensive.
