If you don't like a chemical company, a media company or an arm of the state of Israel sponsoring cycling teams, you're getting pretty darn picky.
Israel Startup Nation is owned by Sylvan Adams, it's not an arm of the Israeli state. He is a real-estate billionaire who moved to Israel in 2015 and has been promoting cycling there since (he's also won a bunch of world masters TT and track titles).
I can see why some people find it distasteful for a cycling team to be promoting a repressive regime (Astana, Bahrain, UAE), or greenwashing mining/polluting companies. They feel that it undermines the idea that cycling is an environmentally friendly transport solution that should be prioritised to help the planet, and these associations damage the brand. They might have a point, but pro cycle racing s a business, and greenwash is one of the main USPs. Aside from that, you mostly have lotteries (gambling sponsorship is a touchy subject), and holiday or DIY companies.
