No it should not. It's as if you said, if Yahoo has a gun, it should fire at Facebook.
Tech companies do not make their living by exploiting their patents directly (as e.g. pharma companies do). They make living from advertising to their userbase. They do patent some things they use to keep and monetize that usebase, but there is no direct relation.
So: Of course they should not sue "by default". It just isn't a winning strategy for them.
so as long as I do a business in tech, I should not care about anyones patents (or IP in that matter) -- just open the patent book and look what I can steal (sorry: take) from others and use it to build my own tech company.
You don't need to open the patent book for that.
Patents are written in such horrible language that you should not bother. The signal to noise ratio is pathetic.
Instead - yes, you just open the HN and look what you cak take from others and use it to build your own tech company. That's what you do. Are you new?
yes I am new. Today I learnt that HN society hates patents and everything related to it (which kind of make sense). Lost 10% of my karma in couple minutes over 3 posts I wrote.
