These articles may as well be US industry plants. Clickbait title, useless content written to discourage people and hope they throw their hands up and abandon all efforts.

Sovereign clouds are an incredibly meaningful first step. Full independence takes decades. China still uses plenty of AMD and Intel chips, does it mean the amount of independence they've achieved is meaningless? That their stacks are just as dependent on the US as those of the EU?

Of course not and even a child could know that. You start with the very end of the chain and hopefully very gradually work your way upwards. Sovereignty is a float, not a bool. If it's a bool its valye is False for all of China, the US and Italy, where in reality each has very different degrees of tech sovereignty. So you do things in order of efficiency, i.e. compare effort needed and how much it moves the sovereignty needle and pick what has the best ratio at this time. Designing and producing your own processors is far down this list.
