I wasn’t implying your method is unethical, I was just making a note for other companies to follow.
The title says “now with crapware” and I personally think something is only crapware if there isn’t an option to not install other software. Maxthon does offer an option to not install Kingsoft PC Doctor and I’m happy with that.
I have used the software before and it’s a good little tool to have on a system. I have no problem with co-promotion or any sort of marketing.
Maxthon is still a browser at heart and has a hardworking team behind it. Any advantage would benefit the browser and their partners equally.
