Has the tech industry always been so cutthroat, or is this a new trend? Maybe I just didn't hear about tech companies lobbying for power in the past?
Here's a link[0] with 2023 lobby spends by industry, but there is no "tech" listing specific. There's an entry for "Internet" listed, which I'm guessing is what you mean by "tech". Another chart[1] breaks down that entry.
If you want to know when each company started to spend money, you could research their public filings.

The roots of the tech sector are PC (the libertarian dream of basically zero-cost startups), telecoms (playground of monopolies and regulatory capture), and ad guys who’s main trick is outrunning society’s ability to understand their business model.
