No proactive person should allow themselves to sit idly by and watch their company be managed into the ground - because then they won't be doing what they love. Just ask any Nationwide pilot - the bitching is generally for a reason, it's not all about T's & C's, although poor remuneration and working conditions are often a symptom of an overall malaise.
In short, there's nothing wrong with constructive criticism - and since pilots have almost zero say in the strategic running of a company, but have to sit by and watch the idiocy reign supreme, combined with the fact this is a 'rumour' network, then yes, you'll see a lot of complaints here. It's pretty logical if you ask me...
