Why did microsoft get sued and why isn't anyone suing apple?

Microsoft got sued for having internet explorer in their OS.
but what did Microsoft do wrong? back then internet explorer was the only browser, and you can freely get any other browser anyways. I admit internet explorer is a crapy browser, but what reason is there for a company being forced to promote products from rival companies?

MSIE the first browser?

No, no, Netscape was the first widely spread modern internet browser, MSIE was developed a few years later (total Netscape ripoff, but ok...), when finally Bill Gates had to admit he was wrong when he claimed the internet wasn't a big thing. Then Microsoft started their very aggressive campaign to let everyone switch to their browser and Netscape collapsed a few years after that. Mozilla Firefox is a totally redesigned version of the Netscape browser btw...

Anyway for nostalgia:

Now look at apple:
Purposely blocking flash, ok maybe flash would have some problems.
So adobe wrote a new program that converts flash code into iPhone code.
Now apple blocks that also, clearly shutting out the rival and make the rival waste so much money to make a product that apple won't allow them to use.

All apple apps must be approved by apple while all desktop programs are not approved by microsoft.
Just why?

Apple used to be a small innocent company some years ago, now they're growing bigger and bigger, and more greedy by the day, just wait... Apple will get it's share of mass criticism one day, I think it already started with the iPad ("oh noes, not another iThingy for more ca$h").

Just wait a few years, things will change for them too.
