- Swiss German and Austrian German didn't make the cut because Switzerland and Austria are on good terms with Germany and don't mind if we call their languages a dialect of German. Not only is that justification to exclude them, they are also not in Google translate for this reason (which this map uses)
- Luxembourg did mind and went to great lengths to get their German dialect recognized as a separate language, is in Google translate, but Wikipedia lists them as only 300k speakers
- Frisian is seen as a distinct language because of how different it is, is in Google translate, but has about 200k speakers
- Similarly, Scottish Garlic is in Google translate has only 70k-200k speakers
The map is consistent if you set the goal of only considering languages that are in Google translate and have at least 500k speakers.
I do think these rules detract from the map. Frisian and Luxembourgish are interesting as "in-between" languages (Luxemburgish has a lot of French influence, Frisian is closer related to English). And Swiss German has many distinct words that are very different from their German counterparts, so for the purposes of this map it really should be a language.

But they can easily switch to more modest verion or even high german if needed.
This is absolutely not true. Bern is the capital and many people travel there for work or other reasons. It's also a dialect very heavily featured on TV (e.g. I remember there was a weather reporter from Bern, don't know if she still does this), a lot of famous politicians are/were from Bern (e.g. former Federal Council member Adolf Ogi) and many famous musicians also sang/sing in this dialect (Mani Matter, Züri West, Gölä, etc.)
Almost all Swiss dialects are mutually intelligible simply due to the high level of exposure to the diversity (and also their relative similarity). There are some people who don't understand Walliserdeutsch well, because it's less represented and also linguistically more removed from the rest - but even that's something you get used to quickly.
Differences between some of them are rather extreme, especially Prekmurje dialects feel like their own language - so we need to fallback to "book" Slovenian when talking with people from different regions.

I think you cannot really compare the minuscule differences between "Standard German", "Austrian Standard German", and "Swiss Standard German" to the differences between English, Irish and Welsh, which are not even from the same language family. Also, the tool is based on Google Translate, and AFAIK Google Translate doesn't differentiate between them.
Comparing the tool to this map [0], it seems to do a pretty good job in capturing all major languages in Europe, while ignoring their dialects.
But I agree that I would be great if you could zoom into the map and also show differences in local dialects. ChatGPT seems to be pretty good at translating to different variants of standard German, or German dialects [1]

For example in Rome a grocery store bag is "busta", but in Milan it is "sachetto" with "busta" being the word they use for an envelope.
