[Qgis-user] Typo? "required ... donation" for training certificates?

[Jonathan Moules]

On the certification page: 
https://www.qgis.org/en/site/getinvolved/certification.html I see this:

"If approved you are required to make a €20 donation to the QGIS project 
for each certificate."

Is the word use "donation" intentional there, or merely a typo? Because 
it's a bit of an oxymoron to have a "required" "donation".
