Content is far more important than spelling as long as the point gets across well enough. I’ve done the same as you only long before when shortcuts like R and U were introduced and persisted. Picking out grammar and spelling errors instead of discussing the topic means you don’t have anything to contribute TO the topic, and lack of content is far worse of a crime than odd spellings.
I have corrected spelling or grammar before, but only as a side note to be helpful, not to ridicule.
Since people began using voice to text dictation, I’ve pretty much ignored spelling errors and the odd placement of commas.
