Scraping itself isn't universally unethical. Google and Bing scraping websites to make information easier to access is fine, and scraping and analysing government data is even better. Public data should be public, after all.

However, the disgusting data brokers that employ most of the custom scrapers, are usually unethical. That's why I don't trust any person or company that admits being involved professionally in "scraping", because most of the time that means "we collect personal information that got leaked elsewhere and sell them on".
