Terms of many licenses require more than just attribution, but also the inclusion of the copyright notices and licenses verbatim. MIT, BSD, MPL, GPL, LGPL, AGPL, etc all require those at minimum. Then there is the application of the licenses themselves. GPL licensed code stipulates that its inclusion in a new work means that the new work must be licensed under the GPL, as well. AGPL and LGPL have similar terms, but with different stipulations.
