Inbound marketing is pretty explicitly about creating high quality content that builds a business's credibility, making prospects more likely to want to engage and buy from said business. Creating slop 'top 10' lists is kind of the opposite, pushing customers away. It's a bit of a stretch, therefore to blame HubSpot for garbage content on the internet - since doing this is the opposite of what they advocated. Grifters are always going to be around looking to make a quick buck with the least amount of effort possible.
