In the end, the expected delay to the release of a congressional report on the power of big tech was only a few hours, but the impact of the 449-page document itself could last for years

Published late on tuesday by the democrat-controlled house of representatives antitrust subcommittee, it amounts to a justification and a road map for what would be the biggest assault on corporate power in the technology industry since the 1990s, according to our reporters in washington and san francisco.

By controlling access to markets, these giants can pick winners and losers throughout our economy. they not only wield tremendous power, but they also abuse it by charging exorbitant fees, imposing oppressive contract terms, and extracting valuable data from the people and businesses that rely on them, it said.

It advocates rewriting us antitrust law so that tech companies could be forced to break themselves up so that they cannot use dominance in one area to harm rivals in another. the republican minority did not support the recommendations, but democrats expect joe biden, should he win the presidential election, and a new congress to take them up.

Amazon, apple, facebook and google are each accused of choking off competition unfairly in different ways. the report alleges amazon routinely uses third-party seller data to help improve and sell its own products. apple allegedly uses its dominant app store to benefit its own applications and hinder those made by rival companies.

Facebook had maintained its monopoly through a series of anti-competitive business practices, including buying up potential rivals such as instagram. google had demanded that smartphone makers using its android operating system should install its chrome web browser as standard.

These firms have too much power, and that power must be reined in and subject to appropriate oversight and enforcement. our economy and democracy are at stake, said the chairs of the judiciary and antitrust committees.

The ft view is that surveys show consumers fret about data privacy and, indeed, about whether the tech giants are too powerful but enjoy the innovations, free-to-use services and often lower prices they provide.
