Part of the issue is that instead of creating traditional jobs that come with healthcare, benefits, strong legal protections, training and company car/whatever, the platform 'task economy' businesses often cut out these benefits and treat everyone like piece workers. So whereas previously eg a customer service rep got low wages but at least their tax was done for them and they had health benefits, now they get a low wage and have to do all that themselves. There's little chance of on-the-job development and training because all the business needs is more tech engineers to polish a front end or analyse data. Their workload (and therefore wages) can go up and down randomly leaving them out of pocket. All the while it puts some traditional businesses out of business because they can't compete on price/service with these companies, so ultimately there are less and lower quality choices. It pushes the burden of doing business down onto the workers rather than up towards richer investors. I'm not saying this 100% applies to Magic, but it's a general and very valid criticism of this type of "the Uber of X" business.
