Tech industry giant Microsoft has cut ties with the American Legislative Exchange Council (ALEC) and is no longer funding the organization.

Microsoft was a member of ALEC’s Communications and Technology Task Force. It has been reported that Microsoft left because of ALEC’s effort to block the development of renewable energy.

Other big technology companies such as Google, eBay, Facebook and Yahoo still belong to ALEC.

Founded in 1973, ALEC supports free market principles and courts financial support from various foundations, including those controlled by the billionaire Koch Brothers.

A Washington, DC-based politically ultra-conservative non-profit, ALEC thrives on operating in the shadows of American government to push anti-worker, anti-union legislation in statehouses across the country.

ALEC has been advocating policies that hurt fire fighters and other public workers, including encouraging more states to consider shifting to defined contribution plans such as 401(k)-style plans and away from traditional “defined benefit plans.”

ALEC sponsors private meetings allowing state lawmakers and corporate executives to frame legislation that is later introduced in state legislatures. The laws tilt in the favor of big business. ALEC has pushed legislation that has been harmful to fire fighters’ right to collectively bargain and has also proposed other anti-union policies.

Other companies that recently parted ways with ALEC include:

AstraZeneca

Ameren

Berkshire Hathaway Energy

Alliant Energy

PG&E
