I'm sure there are some closed softwares left worth paying for but personally I would stop paying for all of it.
The only software left that I pay for is phpstorm and it's buggy as hell and for every bug report I get a "well, nobody really cares". Then what the hell am I paying for?
Well I'm paying for features not found in other systems but seriously, it soeerds my work up by 300% and slows it down by 200% due to the extreme amount of bugs.. it's not acceptable for a paid product but unfortunately there is no good alternative open source product yet.
