The payload reminds me of '90s-era malware: more intent on just trashing up the system than with gaining any sort of profit. Wiping random people's MBRs isn't exactly nice, but considering that's all it really does, it's a far cry from what most malware seems to be concerned with doing nowadays.
I think many website operators do not see a problem with lying when it helps them getting more pageviews, signups or money.
In September 2015, Imgur distributed malicious JavaScript that targeted users of 8chan. Imgur fixed the vulnerability, but still displayed the following message when JavaScript was turned off:

We would never do anything bad or malicious with our JavaScript, and if you ever run into any problems then feel free to contact us.
