I absolutely despise presumptious software that feels entitled to my attention as and when it chooses. I have my browser set up to wholesale reject all push notifications, I don't let the vast majority of my apps send me push notifications, and any application that feels entitled to pollute my inbox (email already has an awful signal/noise ratio as a communications medium) with useless email alerts gets uninstalled or unsubcribed from immediately. Frankly browser notifications should never have been a thing, it's just another varient of the spamdemic that plagues the modern software landscape. I'll look at your software when I choose, and if the software starts dictating that it gets removed or silenced without exception. I honestly don't understand how most people stay sane with their phones and laptops pinging and flashing away like a pinball machine all day.
