The French had no biplane fighters in active service during WW2 (
https://en.wikipedia.org/wiki/Blériot-SPAD_S.510). The Kirkland article suggests they had other problems, and even without their other problems, the allies were outnumbered by the Germans.

No, not outnumbered at all. It was atrocious leadership that prevented them from being utilized:
The Battle of France:
10 May-25 June 1940
snip
The French fighter force had available to it during the battle more than 2900 modern aircraft. At no time did it have more than one-fifth of these deployed against the Germans. The operational rate of the fighter force was 0.9 sorties per aircraft per day at the height of the battle. (German fighter units flew up to four sorties per aircraft per day.) Yet in spite of committing only a minor portion of its resources at a low usage rate, the fighter force accounted for between 600 and 1000 of the 1439 German aircraft destroyed during the battle.

Could the French Air Force Have
Seized Command of the Air?
On 10 May 1940, the operational units of the French Air Force committed to the Western Front were heavily outnumbered. The low rate of operations in the French Air Force compared to that of the Germans increased by a factor of four the French inferiority in the air during the first month of the battle. By mid-June, however, the Luftwaffe was exhausted. It had lost 40 percent of its aircraft. Its flyers had been operating above hostile territory without navigational aids and with the certainty of capture in the event their aircraft were disabled. The air and ground crews were working from captured fields at the end of lengthening supply lines. The French, on the other hand, had conducted much less intensive flight operations, were able to recover the crews of disabled aircraft, were falling back on their logistical bases, and were bringing new units on line with brand new aircraft every day.
By 15 June, the French and German air forces were at approximate parity with about 2400 aircraft each, but the French were operating from their own turf, and they had the support of the RAF.
Mastery of the air was there for the seizing, but on 17 June the French air staff began to order its units to fly to North Africa. The justification put forth by the air staff was that the army was destroyed and could not protect the airfields.

Those left behind included all of the air force reserve units--47 observation squadrons and 12 fighter squadrons--and all of the units closely connected with the army (the observation squadrons, the 10 assault bomber squadrons, and 7 night fighter squadrons converted to the ground assault role).31
The behavior of the leaders of the French Air Force before and during the Battle of France suggests that their primary purposes were to protect the regular air force against its domestic adversaries and to ensure its survival after the battle and the expected defeat. Refusing to expand the regular air force, spinning off the dangerous and unglamorous observation mission to the reserves, maintaining a low operational rate, declining to seize command of the air when the Luftwaffe was weak, and selecting only regular air force units and those unconnected with direct support of the army to send to North Africa constitute a coherent pattern. The senior aviators kept their service small, protected the cadres from severe danger, and kept most of the regular air force together out of the Germans' reach. Such decisions suggest a preposterous misordering of priorities in a nation at war but do make psychological and institutional sense when one reflects on both the frustration the aviators had suffered in their struggle to achieve operational independence from the army and the cavalier and callous way in which parliamentary officials had played with their lives, careers, and values.
