Sorry to hear you've been having problem. That's certainly not the intended experience.
There are, however, some claims in your posts that I feel the 'need' to address.
If I search on Google (which is arguably a fair search engine to be used), I get the following:
The first link takes me to: https://docs.particle.io/guide/getting-started/start/photon/
Which highlights the use of the new web-setup: https://docs.particle.io/guide/getting-started/start/photon/#step-2a-connect-your-photon-to-the-internet-using-the-setup-web-application
Followed by an explanation on how to use the Particle app: https://docs.particle.io/guide/getting-started/start/photon/#step-2b-connect-your-photon-to-the-internet-using-your-smartphone
The second Google link takes me to: https://docs.particle.io/guide/getting-started/connect/photon/
Which highlights how you can configure your Photon using the CLI, over USB: https://docs.particle.io/guide/getting-started/connect/photon/#connecting-your-device-1
The third link shows you how to install/use the CLI in a more 'advanced' way: https://docs.particle.io/guide/tools-and-features/cli/photon/
Are you sure this isn't an apples/pears comparison? Does it offer ALL the features Particle offers? Are the modules certified, well supported, a great community, etc? Sure, there are similar boards out there, but they often lack in certain areas that turn out to be a major hassle later on.
Yes, the web-setup, which can be found using the Google search you mentioned. There's also SoftAP...
Furthermore, how exactly are the docs outdated? I only just quickly skimmed it to write this post, but it looked up-to-date to me... If things don't change, there's no need to update them on a weekly basis. "don't fix it if it ain't broken"
