Big Tech is a name given to the largest technology companies in the United States, which dominate consumer computing technology around the world. The individual companies change, but the interests and practices of these companies largely remain the same, and are at odds with many of the principles of permacomputing.

• Big Tech software serves the needs and interests of the company, and their need for profit, first.
• As a result, hardware produced by these companies often follows planned obsolescence, in order to create more commodities to sell for profit
• Software created by big tech tends towards complexity. These are large, bureaucratic institutions with tens of thousands of employees, and knowledge about software produced by these companies is centralized within them, both legally and by virtue of its design
• Big Tech companies may destroy or abandon software that does not align with their current business goals
• Most Big Tech companies follow the model of ?software as a service.
