Any business is going to use whatever funds are available to move forward, including government incentives. The incentives are put in place to accelerate the industry, which is deemed to be in the national and global interest. You can agree/disagree but it's the same for all industries, including fossil fuels, which have received far more subsidies than renewables over the years.
Concerns about the renewable energy supply chain are real, same as with semiconductors pharma (antibiotics use ingredients 100% controlled by China), and anything that uses rare earths. The Inflation Reduction Act limits (over time) renewable energy subsidies to US-sourced equipment (including batteries for EVs, solar panels, etc.) which is driving an absolutely historic shift in the supply chain. A huge amount of manufacturing capacity is being built domestically now, all across the country - it will have a generational impact.
