In fairness Ireland is a small country in a big organisation. Influence is going to ebb and flow, but they're always competing with the big countries interests - France and Germany in particular.
Ireland is the 19th largest country out of 27 with 1.2% of the population.
Germany, France, Italy and Spain account for 57% of the population. They're always going to have an out sized influence even on the commission where each country gets a seat.
The news story is hyperbole. The game in Europe is unchanged and sometimes Ireland will get the roles it wants and sometimes it won't. The commission is just one part of a complex political machine.
