I'm a very, very firm believer on not paying for "subscription" to software. New content, I can understand (I spend about 40€ monthly on several Patreons, mostly comic artists; and I have a couple news subscriptions as well), although I still hate music/tv subscriptions and I don't want Netflix, Spotify or whatever. But for software,
no matter how useful it is, I just refuse to choose between an unbounded price and the possibility of losing it because I don't want to keep paying. For the record, I don't have any problems paying, say, 400€ for Mathematica and things like that (in fact, I haven't pirated anything in a very long time). But I paid once and I can use the software as much as I want without paying again.
For me, it's not about the amount of money, but the peace of mind (no additional bills, no additional shit to renew when I my debit card expires, and most important, I don't need to engage in any bullshit cancellation process). In the rare cases where both a subscription and a single payment is offered, I've done the math and from time to time I actually estimate that I'll spend less money on the subscription (although normally it's the other way around, of course), but even in these cases, I prefer paying upfront. I hate that this is becoming less and less available.
