You don't need Linux to run mostly FOSS

"As a general rule, try to favor things that are plain, simple, and unornamented - there's less to go wrong. As a general rule, we suggest treating app stores for desktop OSes with suspicion and keeping them at arm's length. Apple has integrated its App Store deeply into macOS since 2001's Mac OS X 10.0, but you don't need it, and it's full of things that you can get for free elsewhere."

"Always remember the KISS principle. As a general rule, try to favor things that are plain, simple, and unornamented - there's less to go wrong. Compare OpenAlternative.co, which is snazzy and effects-heavy, with the decidedly low-tech Best FOSS Alternatives, which is very simple and austere. The latter has nothing to sell; it's just a plain, simple categorized list of FOSS tools."

Free, highly usable software exists for major proprietary desktop operating systems, allowing avoidance of subscription-based paid apps without changing the OS. Freshening an older Mac or Windows 10 PC benefits from wiping and installing a clean, bloat-free copy of the OS before adding free alternatives. Favor plain, simple, unornamented apps to reduce failure risk. Use austere, curated FOSS lists rather than flashy sites that may push paid or incompatible tools. Treat desktop app stores with suspicion, since many native apps update independently. On Windows, Ninite provides a safe, easy way to install common free utilities.
