Learn Spanish (Latin America): El dron caro falla, y eso que actualizo el programa. - The expensive drone fails, even though I update the program.

The phrase y eso que always takes the indicative mood because it introduces an established, undeniable fact (a "concessive structure of fact"). Unlike aunque, which takes the subjunctive if the information is hypothetical or just acknowledged background knowledge, y eso que emphasizes that you really do update the program, making the drone's failure surprising or frustrating.

What is the exact nuance of y eso que compared to just using aunque?

While aunque actualizo also translates to "even though I update," y eso que is more expressive and colloquial. It adds a strong sense of contrast, surprise, or complaint. It feels a bit closer to saying "and to think that I update the program!" or "despite the fact that I actually update it!"

Both falla and actualizo are in the present tense. Does this mean it happens repeatedly?

Exactly. Using the present tense for both verbs implies this is a recurring, habitual issue: the drone consistently fails, and you consistently update its software. If this were a one-time past event, you would use the preterite: El dron falló, y eso que actualicé el programa (The drone failed, even though I updated the program).

Why is it el programa (masculine) when the word ends in "-a"?
