I feel like you're nit-picking this to depth. Most of the answers you've mentioned may not exist on the homepage but within one click. Under the Product menu, there's a bunch more contextual detail.

I'm not sure why you would expect the main page to list, individually, 30+ types of content. Do you similarly complain that the homepage for Lightroom doesn't say that you can edit the following parameters on an image:

* Lens Correction - Chromatic Aberration, Profile Corrections, Distortion, Vignetting

* Basic - Color Profile, White Balance, Temperature, Tint, Tone, Exposure, Contrast, Highlights, Shadows, Whites, Blacks, Texture, Clarity, Dehaze, Vibrance, Saturation

* Transform - Auto, Guided, Level, Vertical, Full, Rotation, Aspect, Scale, X Offset, Y Offset

* Tone Curve - Regional and Global Highlights, Lights, Darks, Shadows, Point Curves

* HSL / Color - Change hue for Red, Orange, Yellow, Green, Aqua, Blue, Purple, Magenta. Change saturation for same. Change Luminance for same.

* Split Toning, Highlights (Hue, Saturation), Shadows (same), balance between two.

* Details: Sharpening (amount, radius, detail, masking), Noise Reduction (luminance, detail, contrast)

... and so on.

Or do you settle for "Wide ranging, comprehensive non-destructive image editing"?

> What are these 30 types of content? It doesn't even give examples.

There are, just off the main page.

I'm just not sure what you're expecting is at all reasonable of any product. The main page draws you in, and the Product page breaks it down by use context. You're certainly entitled to "I don't want to have to go to any additional pages", but that doesn't work for anything more than the simplest products.
