You can see here:
@alzhao Said that USB150 and N300; 2 of the products you own; are EOL. The post you linked to was from the beginning of the year, the one i linked is more recent from August. They are not wild guesses, only factual statements directly from Alfie.
Having a lot of stock that lasts many years and the product no longer being manufactured are two different things. EOL and not offering support are also different things. But as before, unless @alzhao says otherwise, products have gotten updates at least 2 years after EOL, so take that or leave it. Since you asked to a reply i made, and it’s a public forum, you can talk to Alfie in private if you are not satisfied.
