If you aren't putting the effort in to verify anything or doing enough research to even like, see if there is an existing app or that this app is related to the real website, then you simply can't claim--as Apple does--to be screening the apps that are submitted for scale. Like, are you suggesting that the goal of the App Store's walled garden is merely to prevent obvious scams?!
I am expecting the reviewer to spend a moment at least searching their own store for LastPass, in addition to searching Google and checking the credibility of the submitter. Why, pray tell, do you think the reviewer even deserves to exist if they cannot block this sort of scam, due to something as trivial a reason as "they hadn't personally heard of LastPass"? There is a good reason why the FTC has finally decided to call bullshit on companies like Apple who claim their centralized closed ecosystem and resulting anti-competitive market manipulation is "required" for safety / security: you even used to work for Apple, and are essentially admitting they can't possibly do this function!!
This is human judgment. There are going to be failures. I believe a closed ecosystem is safer. You do not. Great! Let's each support the company that gives us that. <3
