Imagine I have a business where I busk for money with my guitar outside of a coal plant and a single coal minor is my patron. I may be "carbon neutral" but in fact I owe my whole existence to coal being mined and burnt. Coal is my life blood and the sole source of wealth in my life. I may as well mine the coal myself and play guitar for myself, and if you consider me and the miner to be a unit it's obvious the two of us are living on coal and the fact that he does all the work while I play guitar hardly means anything.
Companies like stripe are sufficiently separated from coal and oil that they can believe they don't suck at the teat of fossil fuels, and that the only coal wealth they consume is whatever powers their light bulbs and servers. But ultimately you can track back the wealth that comes their way - all of it - to operations that generate quite a bit more emissions.
We can run subsidies and credits in little isolated corners of our economy, but it's like running a refrigerator in a closed room. Ultimately you're just burning wealth which creates a greater load on the wealth-generating machine that is the fossil fuel industry.
Real advances that make it possible to generate wealth without fossil fuel money in subsidies should be celebrated. These tech guys taking $1m of their $100m in profits (the coal miner pays the busker using stripe) to pay their $1m light bill is a shell game
