Thanks for doing that.
IMHO it’s show, don’t tell. I’m assuming you have few laptops laying around here but ideally :
- have a working Linux computer and let them play with it. You can have few documents on the desktop to help kickstart the process, few browser tabs opened with e.g. ProtonDB to show that most games do work, etc. A little “trick” you can do is have an email client (Web based or not) opened so that they can (if they want) email to themselves a message like “I wrote this on Linux!” and a link to some documentation your wrote online about the event.
- have another one where you can do an installation live (or play in loop a few minutes video recording where disk formatting, package download and installation, are sped up, easy to do with a VM)
- have yet another one where … they can install themselves! I’d suggest a VM there so that they don’t fear they would wreck your computer
Few “gotcha” I would warn people who are genuinely interested in (as I wouldn’t waste time with this for people still doubting) :
- backup your data (documents, family photos, work, etc but NOT games, music, downloaded movies) on a USB stick before you do anything!
- you might have to tinker with BIOS settings but that is not scary BECAUSE you backed up your data
- there are plenty of distributions, even though that’s beautiful, … just pick a popular one at first because that’s how you get help more easily
- peripherals are not all made equal, even though the vast VAST majority do work with Linux, they don’t have little stickers to help customers buy them so rely on standards (like BlueTooth or WiFi) AND if it’s something expensive or bulky, do check online reviews with product name + linux in a search engine like DuckDuckGo.
Now… the actual argument I usually share with people is the browser. Most people don’t use their computer, really. They use their browser to connect to the Web THEN do their “work” or entertainment. In that case then it should be no problem because browsers are properly cross platform. I would let them potentially use Chrome (sigh) or Chromium just to show how familiar it is and hope that, as they learn more about freedom, they do consider other browsers, like Firefox or WaterFox, Pale Moon, etc but just like with distributions, starting with whatever is popular and they feel comfortable with.
My hope is actually that standard compliant (that’s the important bit) hardware keys and passkey, e.g. WebAuthn, get more broadly accepted. This way open source and hope hardware solutions, e.g NitroKey, would allow anybody on any OS supporting those standards (which does include Linux without proprietary blobs AFAICT) to work.
