You're partially right. It's possible to be an informed fan of this band and still be against it. I was using the 'you' as in the guy I was referring to, not 'You' as a stand-in for everyone, but I see how you interpreted the response. I was acknowledging other people's legitimate claims and contrasting them with this guys'.
The second part stands for anyone. Narrowing it down to this band - 60% of the band have infants, they've hit snags in releasing music in the past, and are 15 years into their lifespan. Combine those facts with their album sales trend & a potentially stunted tour season, do you really see more coming from them?
Through that lens, I say have at it. Bands like to record & tour. That is their default preference. After 15 years, this band has earned the right to use any resources they may attract for work done in that time. If they fail, so be it.
