Rather than have to carry hymnbooks between home and church I have copies at home and at church. I don’t blame the publishers for this situation. I have had Sibelius installed on my laptop for 7 years. I carry the laptop around with me so I don’t need two licences. If I wanted to use Sibelius (or Dorico) on a church computer I’d get the church to buy a licence. Given the power of the software I consider it very cheap. €600 would pay for about 15 hours of a professional copyist’s time.
