I assume because it's cheaper and easier, but I was surprised to hear that too.

Not sure how real this survey is, but they say 83% of households do a fake tree.

Use Google Collab or another web hosted platform. If you're unfamiliar Google Collab is a part of Google docs that you can run Jupyter Notebooks on (and it's free). This avoids the need for anyone to install anything and means you can test materials in the same environment everyone will run against.
Additionally, Jupyter notebooks makes it easy to add markdown, so instructions can be in stylized format and the students can run the cells over and over again to see how the output changes in real time.
Lastly, I would lean towards python, but there are many different languages supported in Google Collab and similar web hosted tools.
Funnyjunk? Just checked and it's still around, not sure if it matches what you're looking for.
