But that ad is ridiculous, because it shows absolutely nothing of value.
I think I disagree with you here. The ad shows:
- Ligature support
- Themeing
- Integration with WSL
- that Windows Terminal is open source ("Check out our github!" at 0:21)
- Hyperlink support
- Unicode support (implied by the emoji)
- Some sort of package manager specifically for Windows Terminal extensions? (0:20)
Which are all features that could conceivably be valued by developers. At the very least it gets across the point that "Yeah, CMD is shit, but fear not! Now there's a first-party terminal that doesn't suck!". There's no denying that all of this is presented in an "emotion-based" format as you put it, but I would argue that it's a good balance between informative and entertaining. Heck, I much prefer it to the ads you get nowadays on youtube where you can't even tell what they hell they're trying to sell to you.
