I upvoted you because I appreciate the sentiment a lot.
As a non-native speaker in my country, if I seek to participate in meetups, etc. with the expectation that the language used will be the local one, I would prefer not to switch to English. I deliberately go to tech meetups partly for that purpose. It's fine to switch to English if the presentation is specifically in English, but I do not want the audience to accommodate to my lacking; I'd rather be clueless than be accommodated.
