Unfortunately all the flagships oned have decided one port is enough.

Customers showed them it's enough. I don't blame the companies for it. Supply and demand. Why add features in your devices that only cost you more money to implement when removing it has no effect on the sales.

As for consumer repairs, I wouldnt be surprised if it becomes completely impossible soon

Consumers will be able to choose between repair or replacement of defective products within the two-year legal guarantee period. Companies will have to repair a product for free within that period, if cheaper than a replacement, and continue to offer affordable repairs for five to 10 years after a product's sale even if it is outside of the guarantee.

Manufacturers and distributors will also have to inform consumers of their right to have products repaired and offer spare parts to independent repairers at reasonable prices.
