The main issue is the fact that the wiki just does not have enough resources to support having more than just the English language. It would be nice to support having more languages and thus covering more anti-consumer incidents in non-English parts of the world.
Realistically speaking, it would be unfair to run a wiki with additional languages where the volunteer staff are unable to actually moderate the content because they can't understand the language.
The European Council of Engineers Chambers is seeking to standardise training programmes, beginning with the civil engineering sector: https://www.ecec.net/what-we-do/common-training-framework/.
Hopefully, this convergence will extend to other engineering professions.
It's a pity that pages cannot be created in other languages, given that anti-consumer practices also occur outside the English-speaking world.
