Alright so lets get technical here.
MB's definition of a PUP
obtrusive, misleading, or deceptive advertising, branding, or search practices
does not apply to CheatEngine or CheatHappens
using pop-ups, pop-unders, ad-insertion, ad-overlays, ad replacement
Also does not apply to either
excessive or deceptive distribution, affiliate or opt-out bundling practices which may or may not include SEO poisoning techniques
Does not apply
aggressive or deceptive behavior especially surrounding purchasing or licensing, including using affiliates & third parties who use different tactics or techniques to get users to purchase, than what is available from the manufacturer's website
Yeah, does not apply
unwarranted, unnecessary, excessive, illegitimate, or deceptive modifications of system settings, security settings or configuration (including browser settings and toolbars that bring no additional value over standard Operating System and legitimate application settings)
Pretty sure this does not apply
using fake installers for commonly used software (such as Adobe Flash Player) to push your product
Does not apply
using exaggerated findings (such as claiming temp files, cookies, registry entries, etc are harmful) as scare tactics to get users to purchase
Nope, definitely doesn't apply
using technical support scam tactics
difficulty uninstalling or removing the software
predominantly negative feedback or ratings from the user community
in general hurting or diminishing end user experience
other practices generally accepted as riskware, scareware, adware, greyware, or otherwise commonly unwanted software by the user community
Nope Nope Nope Nope And NOPE
So if CheatEngine or CheatHappens does not fit any of this criteria, how exactly do you call it PUP?
CheatEngine does not come bundled with software, it also has no ads to speak of, its also SIMPLE to uninstall.
So i'm curious as to what exactly makes CE a PUP when you actually have to KNOWINGLY Install it, and someone isn't going to install it without knowing what it does. Same goes for CheatHappens, people go there because they know what its about.
