Anyway, you'd be surprised. Once you venture outside the HN echo chamber there are large numbers of people who really prefer that their data stay on their own PC. Also, many are concerned about the same problem that this topic is about: having interfaces change without warning is a huge problem for most people.
Convincing them is largely about providing an upgrade path if they need it and not having forced upgrades.
AFAICT, that's backward: people with that preference are over-, not under-, represented on HN.
[0] anyone who just uses a web browser arguably doesn't even count as a 'desktop computer user'.
My understanding right now is that if you have a software that people need to install and your competitors have an in browser offering, your customers overwhelmingly choose the in browser offering.
This has been my experience even though I hate the subscription model as much as everybody else in this thread
Speaking for myself, I have replaced Adobe CC with Affinity Publisher, Designer and Photo. A one-time fee for software I can use forever, as opposed to paying forever regardless of whether I use it or not.
I also have Dreamweaver and Flash-type animation tools (Bootstrap Studio and Tumult Hype) that are also one-time fee apps.
Yes, this.
Investing all your energy into features none of your users want for an existing app is a waste of energy for you and an annoyance for the users.
And maintaining the backend of a SaaS can mean more operations busywork for you, compared to a standalone application.
Build something new people actually want.
I feel like general computer skills have decayed quite a bit in the general public, especially with people who don't work with computers 8 hours/day. See this recent article: https://www.theverge.com/22684730/students-file-folder-direc... The advent of the smartphone/tablet overtaking PC use for general/casual use, e.g. emails, photos, social media, online banking/billpay has really reduced the general public's skill level with desktop operating systems. Probably similar overlap with the subset of people who always dumped every file to the desktop directory instead of organizing files in specific directories.
Even for IDE I have XCode, Webstorm, Sublime …
In general, native apps are still far superior for most tasks I do.
