Except of course the Ariane chockhold never existed for small rockets. Because Vega exists. And for large rockets the "chokehold" very much continues to exist and shows absolutely zero evidence of going away in the next decade.

So far the support for these small launchers has been mostly for new missions and nowhere near in the volume to support even two of these small launch companies. Specially if Vega also survives as a rocket.

Europe simply does not produce enough launches for these companies. And all of them will suffer from very low launch rates and non will be able to seriously compete for international payloads.
