Yes, but everyone is entitled to their opinions on such matters. And this shows one reason why decisions are made locally. I know of no one in my parish with those opinions, and I am always actively seeking such opinions. On the other hand, if such opinions were the norm, then I guess we would go acapella, though I would ask those whose pitch is good enough to sing without accompaniment to put their voice where their mouth is

and lead it.
Of course everyone is entitled to their personal opinions. That’s the point of a forum.
Our parish is like yours. The people are happy to have any kind of music, and they seem to love guitar, piano, etc…
When anyone desires more traditional music (Latin, pipe organ only), they are free to drive about two miles to attend the local TLM parish, or they can attend one of several parishes within easy driving distance where the OF Mass has gone with more traditional practices (e.g., no contemporary music, more Latin in the Mass, Holy Communion kneeling at an altar rail, no girls serving at altar, etc.).
Or they can attend the 6:30 a.m. Mass on Sundays where there is no music. Lots of people do this, as it works well with little children, and it frees up the rest of the day.
We are fortunate that so many wonderful Mass options are available within easy driving distance!
The one option that we don’t have is a parish with really excellent music done by excellent musicians. Our Catholic parishes in our city do the best we can, but if your motive for attending church is hearing good music, you’ll go to one of the Protestant churches, either the evangelical churches for great contemporary praise or traditional praise Christian music, or the non-denoms for good Christian rock music, or the old Lutheran and other mainline churches for beautiful classical music, or the African-American churches for awesome Gospel music, or the Unitarian “church” for the very best music of all styles (that’s where all our area’s professional musicians hang out and jam).
OTOH, I started my pipe organ lessons last week–maybe in ten years, I’ll be good enough to play something worth hearing for Mass!
