There’s a long Feature Suggestions topic on this, check out this post … if you wish to comment further can I ask you do so in that topic so we don’t drift off topic here.
Roon have previously commented, that whilst lifetime was good for them in the beginning (their startup phase if you like) it’s less so now that their company is more mature. However, at present they still offer a lifetime option for those that preferer it.
We as customers want Roon to be successful, and to be able to continuously develop their product for many years … for that to happen they need regular income to balance the books, a “rent to buy” model I’d suggest is worse case option to achieve that.
Lifetime is available, if that’s what you want go for it. If you need to spread cost then you could look at 3rd party credit options.
It’s fine to have different views, we just ask the people respect one another on here.
