Greg K-H's explanation (as paraphrased by the journalist) confirms that, for example, receiving payment for an article which is accompanied by a software example would not trigger the requirements that come with monetization. Here's the exact quote - look at the "even when" part:

"There is no legal risk for individual contributors simply sharing code online or in publications, even when they receive payment for writing an article, as long as the software itself is not monetized or organized."

So, maybe EU developers would have to learn the safe wording through which to solicit and accept donations, but at the very least, donations supporting their software activities in general (and not tied to a specific software program) will likely not increase CRA requirements - and maybe even voluntary donations to support development of a specific software program but which are not in any way mandatory.
