There are thousands of lawsuits filed against US government each year. No luck involved but a large law firm wouldn’t take cases that would be a waste of time, so they’d have to evaluate the chances and be motivated to fight on behalf of thousands of businesses. No different than the big law firms that won the opioid cases.

You just gave me an idea: could USPS be sued for aiding theft and patent infringement, just like pharmacies were sued for distributing opioids?

Just Google antivirus Black Friday, Microsoft Black Friday, etc

I think you have great imagination and imagine that “everyone is saying that”. Or maybe you’re listening to wrong people because I guess Coca Cola may not be saying that. Find out what Coca Cola is saying and then make a claim that “not everyone is saying the same thing.” But maybe everyone is saying that you need to research a topic to not make false claims about everyone saying something :)
