First question: The higher latency only occurs with VST Instruments. Don't confuse it with audio round trip latency, it's completely different.
The issue is with the time it takes a virtual instrument to generate sound after the MIDI trigger is received in real time. So only when playing a virtual instrument with a (virtual) controller the higher latency (compared to other DAW's) is present. When playing back recorded MIDI data there's no difference with other DAW's. When you never play virtual instruments in real time or quantize everything to the grid it won't be an issue. When low latency, timing (for instance for an e-drummer or someone who's trying to maintain a certain 'feel' in the musical data recording) and minimal CPU strain is important, it could cause an issue.
It's not solved by the way because it's not identified as a bug, so it's a FR you can vote on here True low latency when playing virtual instruments
Second question: Currently there's no subscription model.
