I'm not seeing 24 products in 2018, but just 1 - Encrypted Search.

I just realized you're counting the Others section and incorrectly lumping them into 2018.

It would seem you also neglected to read Wikipedia's banner above the Other section that stated:

This section is missing information about the discontinuation date of each product in this section. Please expand the section to include this information. Further details may exist on the talk page. (October 2013)

but still more than 100 discontinued services...

What does that have anything to do with your original comment? You incorrectly stated there were 24 in 2018 when in actuality there was only 1.
