I understand that sharing video, photos, documents etc. is relatively safe because the data is not executed in the processor as instructions. How come people are willing to download and install pirated software though? How can one be confident that it does not contain malicious addons? Are people just don't know the risks? Or are there protection mechanisms that I am missing? I mean since the software is usually cracked there is not much use in comparing checksums with the originals, is it?

You can just remove "priated" from that statement and come to the same conclusions. Considering the amount of bugs, backdoors and 0-day exploits distributed via official software I sometimes wonder why people execute proprietary, closed source programs at all.
An no, "reputable" companies mean nothing, just look at Microsoft clowning around with their signing keys.
Worth noting that paying for a license for software doesn't stop it being spying malware either. In fact the pirate versions often take out the spying and the reporting-to-homebase that proprietary software does.
The photoshop that phones home to check a license is arguably more malicious than the pirate version that has been cracked so it doesn't do that.
Make a dedicated user on your machine for pirated software. Never give that user root. Should contain it.
