| That's am understandable perspective but wouldn't this more or less apply to any product any large company is selling as part of a bundle? e.g. selling Word/Excel/PowerPoint together is hurting any start-up that might want to enter the document processing/spreadsheet/etc markets? Free browsers killed the entire market that was starting to appear in the 90s etc. etc. Should office suites be banned? Should Adobe be only allowed to sell subscriptions/licenses for individual apps? At the end of the day it should only matter if Microsoft's practices are hurting consumers rather than their competitors. |
Focusing on short term repercussions for consumers has significantly hurt long term consumer interests and there is evidence that it hurt the economy in general. In the decades preceding the 1980s it was generally understood that competition itself is a necessity for effective free markets and that extreme power concentration (as we e.g. see today in the IT sector) is hard to reconcile with efficient markets and political freedom.
See [1] for details, here is an excerpt:
> An emerging group of young scholars are inquiring whether we truly benefitted from competition with little antitrust enforcement. The mounting evidence suggests no. New business formation has steadily declined as a share of the economy since the late 1970s. “In 1982, young firms [those five-years old or younger] accounted for about half of all firms, and one-fifth of total employment,” observed Jason Furman, Chairman of the Council of Economic Advisers. But by 2013, these figures fell “to about one-third of firms and one-tenth of total employment.” Competition is decreasing in many significant markets, as they become concentrated. Greater profits are falling in the hands of fewer firms. “More than 75% of US industries have experienced an increase in concentration levels over the last two decades,” one recent study found. “Firms in industries with the largest increases in product market concentration have enjoyed higher profit margins, positive abnormal stock returns, and more profitable M&A deals, which suggests that market power is becoming an important source of value.” Since the late 1970s, wealth inequality has grown, and worker mobility has declined. Labor’s share of income in the nonfarm business sector was in the mid-60 percentage points for several decades after WWII, but that too has declined since 2000 to the mid-50s. Despite the higher returns to capital, businesses in markets with rising concentration and less competition are investing relatively less. This investment gap, one study found, is driven by industry leaders who have higher profit margins.
