No need to be scared about Apple's data collection without your consent.
There's a very simple patch you can use to stop this activity in macOS Mojave through Big Sur. Open up Terminal and copy and paste the following:
echo "127.0.0.1 ocsp.apple.com isrg.trustid.ocsp.identrust.com" | sudo tee -a /etc/hosts

An easier to read version for those using 4 or 5K monitors.
echo "127.0.0.1 ocsp.apple.com isrg.trustid.ocsp.identrust.com" | sudo tee -a /etc/hosts
To undo, run this terminal command:
sudo sed -i "" "/ocsp\.apple\.com/d" /etc/hosts
For those still running High Sierra or older macOS versions you don't need to use the patch to stop this. It only started after macOS Mojave was released.
