I'd rather have a full range of 100 titles in unlimited volume available for 24 hours at 50% off.

IIRC, you get this type of sale at least three times a year here on GOG, not just for 24hrs, but for the duration of the sales and with almost their whole catalogue on offer. You also get it every single weekend, and usually with higher discounts than 50%. And then there are also the Classic Gem Promos (every Monday) and the Indie Gem Promos (every Wednesday) that run for 24hrs with no volume limitations and usually at higher discounts as well.
As stated during the previous Insomnia Sale - not every single kind of sales appeals to every single person on GOG, nor is it necessary to. It's definitely appealing to a good number of people, i.e. it's targeting that specific customer base and it's working well.
I really don't get the frustration over this particular type -it's not mandatory to participate and it's quite easy to ignore.
Just my 2c
