I love those classic tools from the likes of Sysinternals or Nirsoft. I didn't hesitate to give them full access to my machine, because I was confident they'd (mostly) work as expected. Although I couldn't inspect their source, I could reason about how they should behave, and the prevailing culture of the time was one where I knew the developers and myself shared a common set of expectations.
Their creators didn't tend to pull stunts like quietly vacuuming all your data up to themselves. When they did want feedback, they asked you for it first.
There wasn't such a potent "extract value" anti-culture, and successful companies recognized enduring value came from working in the user's best interest (eg. early Google resisted cluttering their search results).
Although silos existed (like proprietary data formats), there was at least an implicit acknowledgement and expectation you retained ownership and control over the data itself.
Distribution wasn't locked behind appstores. Heck, license enforcement in early Office and Windows was based on the honour system - talk about an ecosystem of trust.
One way to work toward a healthier zeitgeist is to advocate tirelessly for the user at every opportunity you get, and stand by your gut feeling of what is right - even when faced with opposing headwinds.
