The new owner didn't stop development, they rather worked in 2023 to release this new version 15 Beta. Very long time but better late release than never
Of course, we never know what happens with SpyShelter's userbase in the future, but as said by
@Shantir it is the same case even for other software...
I tried to inform you earlier in this thread. Spyshelter's Application Control makes it's different from basic AVs like the free ones Avira, Avast, Bitdefender Free, MD.
If you are using CyberLock and paid for your license, then you don't need Spyshelter, otherwise all would be "overkill".
Regarding the upcoming test by
@Shadowra I doubt Spyshelter is able to protect fully the system, manually user intervention is required to block or quarantine threats.
As recommended, Spyshelter should be used together with an basic AV, in combo it's more likely to be protected.
More advanced paid AVs has enough protection features, e.g. Kaspersky, Bitdefender, F-Secure and others...
