Not about validation
Issues like SQL/script injection and XSS are not really a problem with input validation, but a lack of proper quoting/escaping of arbatrary data during its use. Yes, input validation can limit/mitigate some attacks, but this also tightly couples the input code and processing code (e.g. the input side assumes SQL queries are used at some point, and the query side code assumes input validation have done for all potential sources).

In general, providing an input with an apostrophe should be considered valid, even if the backend uses this value in an SQL query (as the real data being search may have such values, e.g. Name: O'Neill). If I include the text "<grin>" with-in some online forum post/comment, it shouldn't be rejected/removed for no-HTML input fields, but be treated as verbatuim text that is properly escaped in output HTML.

Input validation should normally only be done for specific business logic (e.g. usernames are limited to ASCII letters/numbers and must start with a letter), or general sanity checks (e.g. only ASCII; only valid UTF-8 encoded strings; doesn't contain invalid UNICODE composed sequences; no embedded NUL characters [when using length specified strings]).

No fixes
Moreover, researchers are often incentivized against responsible disclosure simply because the companies won't even listen to them and give them the time of day -- unless it gets national media attention. (Examples: Panera, Apple FaceTime bug, Facebook, etc.)
